The Table Access Protocol (TAP) lets you execute queries against our
database tables, inspect various metadata, and upload your own
data.
In GAVO's data center, we in particular hold several large
catalogs like PPMXL, 2MASS PSC, USNO-B2, UCAC4, WISE, SDSS DR16,
HSOY, and several Gaia data releases and ancillary resources for
you to use in crossmatches, possibly with uploaded tables.

an object at ra/dec with proper motion pmra/pmde has after epdist years.
positions must be in degrees, PMs in should be in julian years (i.e., proper
motions are expected in degrees/year). pmra is assumed to contain
cos(delta).
This function goes through the tangential plane. Since it does not have
information on distance and radial velocity, it cannot reconstruct
the true space motion, and hence its results will degrade over time.
This function should not be used in new queries; use ivo_epoch_prop
instead.returns the authority part of an ivoid (or, more generally a URI).
So, ivo://org.gavo.dc/foo/bar#baz becomes org.gavo.dc.
The behaviour for anything that's not a full URI is undefined.gavo_ipix returns the q3c ipix for a long/lat pair (it simply wraps
the 13c_ang2ipix function).
This is probably only relevant when you play tricks with indices or
PPMXL ids.gavo_match returns 1 if the POSIX regular expression pattern
matches anything in string, 0 otherwise.returns the intersection of two MOCs.returns the union of two MOCs.returns the spectral value expr converted to dest_unit.
expr has to be in either energy, wavelength, or frequency, and dest_unit
must be a VOUnit giving another spectral unit (e.g., MHz, keV, nm, or
Angstrom). This is intended to let users express spectral constraints
in their preferred unit independently of the choice of unit in the
database. Examples::
gavo_specconv(obscore.em_min, "keV") > 300
gavo_specconv(obscore.em_max, "MHz") > 30
gavo_specconv(spectral_start, "Angstrom") > 4000
There is a variant of gavo_specconv accepting expr's unit in a third
argument.returns expr assumed to be in expr_unit expressed in dest_unit.
This is a variant of the two-argument gavo_specconv for when
the unit of expr is not known to the ADQL translator, either because
it because it is a literal or because it does not look like
a spectral unit. Examples::
gavo_specconv(656, 'nm', 'J') BETWEEN spectral_start AND spectral_end
gavo_specconv(arccos(phi)*incidence, 'Hz', 'eV')
Clearly, overriding known units is likely to yield bad results;
the translator therefore warns if an existing unit is overridden
with a different unit.returns 1 if matchagainst is term or narrower in the IVOA vocabulary
vocname, 0 otherwise.
This is intended for semantic querying. For instance,
gavo_vocmatch('datalink/core', 'calibration', semantics) would be 1
if semantics is any of calibration, bias, dark, or flat.
For RDF-flavoured vocabularies (strict trees), term will expand to the
entire branch rooted in term. For SKOS-flavoured vocabularies (where
narrower is not transitive), only directly narrower terms will be included.
Both the term and the vocabulary name must be string literals (i.e.,
constants). matchagainst can be any string-valued expression.Returns a 6-vector of (ra, dec, parallax, pmra, pmdec, rv)
at out_epoch for these quantities at ref_epoch.
Essentially, it will apply the proper motion under the assumption of
linear motion. Despite the name of the positional parameters, this is
not restricted to equatorial systems, as long as positions and proper
motions are expressed in the same reference frames.
Units on input and output are degrees for ra and dec, mas for parallax,
mas/yr for pmra and pmdec, and km/s for the radial velocity.
ref_epoch and out_epoch are given in Julian years.
parallax, pmra, pmdec, and radial_velocity may be None and will enter
the computations as 0 then, except in the case of parallax, which
will be some small value. When abs(parallax) is smaller or equal
to that small value, parallax and radial velocity will be NULL on
output.
In daily use, you probably want to use the ivo_epoch_prop_pos functions.Returns a POINT giving the position at out_epoch for an object
with the six parameters at ref_epoch.
Essentially, it will apply the proper motion under the assumption of
linear motion. Despite the name of the positional parameters, this is
not restricted to equatorial systems, as long as positions and proper
motions are expressed in the same reference frames.
Units on input are degrees for ra and dec, mas for parallax,
mas/yr for pmra and pmdec, and km/s for the radial velocity.
ref_epoch and out_epoch are given in Julian years.
parallax, pmra, pmdec, and radial_velocity may be None and will enter
the computations as 0 then, except in the case of parallax, which
will be some small value.A variant of ivo_epoch_prop_pos that behave as if parallax
and radial_velocity were both passed as NULL.The function transforms ADQL geometries between various reference systems.
geo can be a POINT, a CIRCLE, or a POLYGON, and the function will return a
geometry of the same type. In the current implementation, from_sys and
to_sys must be literal strings (i.e., they cannot be computed through
expressions or be taken from database columns).
All transforms are just simple rotations, which is only a rough
approximation to the actual relationships between reference systems
(in particular between FK4 and ICRS-based ones). Note that, in particular,
the epoch is not changed (i.e., no proper motions are applied).
We currently support the following reference frames: ICRS, FK5 (which
is treated as ICRS), FK4 (for B1950. without epoch-dependent corrections),
GALACTIC. Reference frame names are case-sensitive.The function takes two strings; the first is a list of words not
containing the hash sign (#), concatenated by hash signs, the second is
a word not containing the hash sign. It returns 1 if, compared
case-insensitively, the second argument is in the list of words coded in
the first argument. The behaviour in case the the second
argument contains a hash sign is unspecified.gavo_hasword returns 1 if needle shows up in haystack, 0 otherwise. This
is for "google-like"-searches in text-like fields. In word, you can
actually employ a fairly complex query language; see
https://www.postgresql.org/docs/current/textsearch.html
for details.returns a POINT corresponding to the center of the healpix with
the given index at the given order.Returns the index of the (nest) healpix with order containing the
spherical point (ra, dec).
An alternative, 2-argument form
ivo_healpix_index(order INTEGER, p POINT) -> BIGINT
is also available.The aggregate function returns a histogram of val with nbins+2 elements.
Assuming 0-based arrays, result[0] contains the number of underflows (i.e.,
val<lower), result[nbins+1] the number of overflows. Elements 1..nbins
are the counts in nbins bins of width (upper-lower)/nbins. Clients
will have to convert back to physical units using some external
communication, there currently is no (meta-) data as lower and upper in
the TAP response.The function returns 1 if the interval iv contains val, 0 otherwise.
The lower limit is always included in iv, behaviour on the upper
limit is column-specific.The function returns 1 if the interval [l1...h1] overlaps with
the interval [l2...h2]. For the purposes of this function,
the case l1=h2 or l2=h1 is treated as overlap. The function
returns 0 for non-overlapping intervals.ivo_nocasematch returns 1 if pattern matches value, 0 otherwise.
pattern is defined as for the SQL LIKE operator, but the
match is performed case-insensitively. This function in effect
provides a surrogate for the ILIKE SQL operator that is missing from
ADQL.
On this site, this is actually implemented using python's and SQL's
LOWER, so for everything except ASCII, your mileage will vary.The function returns a random number drawn from a normal distribution
with mean mu and width sigma.
Implementation note: Right now, the Gaussian is approximated by
summing up and scaling ten calls to random. This, hence, is not
very precise or fast. It might work for some use cases, and we
will provide a better implementation if this proves inadequate.gavo_simbadpoint queries simbad for an identifier and returns the
corresponding point. Note that identifier can only be a literal,
i.e., as simple string rather than a column name. This is because
our database cannot query simbad, and we probably wouldn't want
to fire off millions of simbad queries anyway; use simbad's own
TAP service for this kind of application.An aggregate function returning all values of
expression within a GROUP contcatenated with delimiterThe function converts a postgres timestamp to julian date.
This is naive; no corrections for timezones, let alone time
scales or the like are done; you can thus not expect this to be
good to second-precision unless you are careful in the construction
of the timestamp.The function converts a postgres timestamp to modified julian date.
This is naive; no corrections for timezones, let alone time
scales or the like are done; you can thus not expect this to be
good to second-precision unless you are careful in the construction
of the timestamp.Written after a table reference, TABLESAMPLE(10) will make the database only use 10% of the rows; these are `somewhat random' in that the system will use random blocks. This should be good enough when just testing queries (and much better than using TOP n).A geometry function creating MOCs. It either takes a string argument with an ASCII MOC ('4/13 17-18 8/3002'), or an order and another geometry.You can compute with vectors here.

bgdsBGDS time series
From the Bochum Galactic Disk Survey, time series have been obtained in the
r and i bands on an (up to) nightly basis. Depending on the field, the time
series contain up to more than 300 nights over more than 7 years. Each
measurement represents the averaged flux over 10 minutes of observation
(from 9 averaged 10s images).
The Bochum Galactic Disk Survey is an ongoing project to monitor the
stellar content of the Galactic disk in a 6 degree wide stripe centered on
the Galactic plane. The data has been recorded since mid-2010 in Sloan r
and i simultaneously with the Robotic Bochum Twin Telescope (RoBoTT) at the
Universitaetssternwarte Bochum near Cerro Armazones in the Chilean Atacama
desert. It contains measurements of about 2x10^7 stars over more than seven
years. Additionally, intermittent measurements in Johnson UVB and Sloan z
have been recorded as well.bgds.data The Bochum Galactic Disk Survey is an ongoing project to monitor the

califadr3CALIFA (Calar Alto Legacy Integral Field spectroscopy Area) survey DR3
The Calar Alto Legacy Integral Field Area (CALIFA) survey provides
spatially resolved spectroscopic information for 667 galaxies, mainly
within the local universe (0.005 < z < 0.03).
CALIFA data was obtained using the PPAK integral field unit (IFU), with a
hexagonal field-of-view of 1.3 square arcmin, with a 100% covering factor
by adopting a three-pointing dithering scheme. has been taken in two
setups: V500 (6 Å bin size, 646 galaxies) and V1200 (2.3 Å bin size, 484
galaxies). A final product ("COMBO") combining both data sets, covering
3700-7500 Å at 6 Å bin size, is made availble for 484 galaxies.
CALIFA is a legacy survey, intended for the community. This is the (final)

volume-complete sample of stars in the solar neighbourhood. The CNS5
is compiled based on trigonometric parallaxes from Gaia EDR3 and
Hipparcos, and supplemented with astrometric data from Spitzer and
ground-based surveys carried out in the infrared. The CNS5 catalogue
is statistically complete down to 19.7 mag in G-band and 11.8 mag in
W1-band absolute magnitudes, corresponding to a spectral type of L8.
Continuous updates of observational data for nearby stars from all
sources were collected and evaluated. For all known stars in the 25 pc
sphere around the Sun, the best values of positions in space,

gaia.dr2epochfluxGaia DR2 epoch fluxes
A table of the light curves released with Gaia DR2 (about half a million
in total). In each Gaia band (G, BP, RP), we give epochs, fluxes and
their errors in arrays. We do not include the quality flags (DR2: “may
be safely ignored for many general purpose applications”). You can
access them through the associated datalink service if you select
source_id. You will usually join this table with gaia.dr2light.
We have also removed all entries with NaN observation times; hence,
the array lengths in the different bands can be significantly different,
and the indices in transit_ids do not always correspond to the
indices in the time series.
Furthermore, we only give fluxes and their errors here rather than
magnitudes. Fluxes can be turned into magnitude using::
mag = -2.5 log10(flux)+zero point,
where the zero points assumed for Gaia DR2 are
25.6884±0.0018 in G, 25.3514±0.0014 in BP, and
24.7619±0.0019 in RP (VEGAMAG).550737source_idUnique source identifier.

This is a “light” version of the full Gaia DR2 gaia_source table,
containing the original astrometric and photmetric columns with just
enough additional information to let careful researchers notice when data
is becomes uncertain and the full error model should be consulted. The
full DR2 is available from numerous places in the VO (in particular from
the TAP services ivo://uni-heidelberg.de/gaia/tap and
ivo://esavo/gaia/tap).
This table also includes a column containing the Renormalized Unit Weight
Error RUWE (GAIA-C3-TN-LU-LL-124-01), a robust measure for the
consistency of the solution.
On this TAP service, there is the table gdr2dist.main containing

Therefore a large value of this factor for a given source indicates systematic errors in the BP and RP photometry.stat.fit.goodnessfloatnullableastrometric_excess_noiseThis is the excess noise of the source, measuring the disagreement, expressed as an angle, between the observations of a source and the best-fitting standard astrometric model (using five astrometric parameters).

gaia.edr3liteGaia eDR3 source catalogue "light" This is a “light” version of the full Gaia DR3 gaia_source table. It
is just a view copying gaia.dr3lite, which should preferentially be
used in new queries. This table is being kept around in order to keep
legacy queries from breaking unnecessarily. However, it is actually
DR3 data rather than eDR3. The minute differences did not seem to

gdr2apAstrophysical parameters from Gaia DR2, 2MASS and AllWise We estimated the stellar astrophysical parameters of 120 million
stars over the entire sky that have Gaia parallax and photometry from
Gaia DR2, 2MASS, and AllWISE. We provide estimates of log age, log
mass, log temperature, log luminosity, log surface gravity, distance
modulus, dust extinction (A0), and average grain size (R0) along the
lines of sight. In contrast with other catalogs, we do not use a
Galactic model as prior but weakly informative ones. Our estimate and
uncertainties are quantiles, so they are invariant under monotonic
transformations (e.g., log, exp). This means that one can use our
median estimate to obtain the median distance or temperature, for
instance, and likewise for the uncertainties.gdr2ap.main We estimated the stellar astrophysical parameters of 120 million

gedr3distGeometric and photogeometric distances to 1.47 billion stars in Gaia
Early Data Release 3 (eDR3)
We estimate the distance from the Sun to sources in Gaia eDR3 that have
parallaxes. We provide two types of distance estimate, together with
their corresponding asymmetric uncertainties, using Bayesian posterior
density functions that we sample for each source. Our prior is based
on a detailed model of the 3D spatial, colour, and magnitude
distribution of stars in our Galaxy that includes a 3D map of
interstellar extinction.
The first type of distance estimate is purely geometric, in that it only
makes use of the Gaia parallax and parallax uncertainty. This uses a
direction-dependent distance prior derived from our Galaxy model. The
second type of distance estimate is photogeometric: in addition to
parallax it also uses the source's G-band magnitude and BP-RP
colour. This type of estimate uses the geometric prior together with a
direction-dependent and colour-dependent prior on the absolute magnitude
of the star.
Our distance estimate and uncertainties are quantiles, so are invariant
under logarithmic transformations. This means that our median estimate
of the distance can be used to give the median estimate of the distance
modulus, and likewise for the uncertainties.

This table gives empirical magnitude limits for
G and BP bands derived from Gaia DR2 with G < 20.7 mag for HEALPixels
of 5 (scale roughly ~2 degrees). For each band
we have 4 different variants:
(1) no additional condition,
(2) parallax available,
(3) BP-RP available,
(4) parallax and BP-RP available.
For BP mag limits we also require that BP is available. The magnitude
limits are approximated by the mode of the magnitude distribution in a
specific HEALpix. Since this mode estimator is prone to Poisson noise
in low density areas we report the magnitude limits in two flavours:
(a) directly the mode estimator
(b) the same as the mode estimator,
except that in healpixel with a stellar density below 1e5 sources per
square degree the limit is arbitrarily set to 20.7 mag. These magnitude
limits were created using the `gdr2_completeness package`_ and users

gedr3mock.maglim_7
This table gives empirical magnitude limits for
G and BP bands derived from Gaia DR2 with G < 20.7 mag for HEALPixels
of 7 (scale roughly ~0.5 degrees). For each band
we have 4 different variants:
(1) no additional condition,
(2) parallax available,
(3) BP-RP available,
(4) parallax and BP-RP available.
For BP mag limits we also require that BP is available. The magnitude
limits are approximated by the mode of the magnitude distribution in a
specific HEALpix. Since this mode estimator is prone to Poisson noise
in low density areas we report the magnitude limits in two flavours:
(a) directly the mode estimator
(b) the same as the mode estimator,
except that in healpixel with a stellar density below 1e5 sources per
square degree the limit is arbitrarily set to 20.7 mag. These magnitude
limits were created using the `gdr2_completeness package`_ and users
are encouraged to create custom-made magnitude limits with specific
conditions, e.g. RVS sample with good parallaxes.

gedr3mock.parsec_propsParsec-based photometry and extinction for GeDR3 Mock This table is intended to augment the Gaia photometry of GeDR3 Mock
stars with other bands and extinctions (Sloan, Johnson and 2MASS). The
grid was generated by binning all isochrones in logg, teff, and feh
and taking the median values of all isochrone models that fall within
one bin. We also report the median values of some astrophysical
parameters so that one can check how far the actual star abundances
deviate from the bin's median. For the extinction we report the
extinction for the specific isochrone bin in a specific photometric
band for 6 different values of monochromatic extinction, A_0, i.e.
1,2,3,5,10,20 mag.
Sometimes stars in GeDR3 Mock depart from the isochrone grid, because,
e.g., the feh value is outside of the grid or values have been
interpolated by Galaxia in the catalog generation from the Parsec
isochrones. Then the index_parsec is assigned to the nearest neighbour
in log_lum and log_teff.243238index_parsecThe primary key of the photometry table, useful for joining with index_parsec in gedr3mock.main.

lswHDAP -- Heidelberg Digitized Astronomical PlatesScans of plates kept at Landessternwarte Heidelberg-Königstuhl. They
were obtained at location, at the German-Spanish Astronomical Center
(Calar Alto Observatory), Spain, and at La Silla, Chile. The plates
cover a time span between 1880 and 1999.
Specifically, HDAP is essentially complete for the plates taken with

plc3Astrometric Microlensing Events Predicted from Gaia eDR3 From the Gaia eDR3 catalogue we predict astrometric microlensing
events by foreground stars with high proper motion (μ > 100 mas/yr)
passing a background source in the next decades. Using Gaia DR3
photometry we determine an approximate mass of the lens, which we use
to calculate the expected microlensing effects. This yields 4842
microlensing events by 3791 different lenses between 2010 and 2066
with expected shifts larger than 0.1 mas between the lensed and
unlensed positions of the source. The past events might be interested
when analyzing the individual Gaia measurements). 685 of those are
expected to happen within the next decade (2021-2031). For 140 events
we also expect a magnification between 1 mmag and 0.6 mag.plc3.dataThe final candidate table for astrometric microlensing events
predicted from Gaia eDR3. This has estimates of minimal distances,
epochs, etc. Columns prefixed with lens_ are for the lens, columns
prefixed with ob_ are for the lensed object.4842event_idUnique identifier of this event.

xpparamsParameters of 220 million stars from Gaia BP/RP (XP) spectra We present astrophysical parameters of 220 million stars, based on
Gaia XP spectra and near-infrared photometry from 2MASS and WISE.
Instead of using ab initio stellar models, we develop a data-driven
model of Gaia XP spectra as a function of the stellar parameters, with
a few straightforward built-in physical assumptions. This resource is
a VO re-publication of the resulting catalog of stellar parameters.

apassAAVSO Photometric All Sky Survey (APASS) DR10
AAVSO Photometric All-Sky Survey (APASS), underway since 2010,
covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY
bandpasses. A northern and a southern site are used, each with twin ASA
20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square
degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for
all-sky solutions, with typical 0.02mag calibration errors on the bright
end.
Data Release 10 is a complete reprocessing of all 500K images taken with
the system, including hundreds of nights not part of DR9. Sextractor is
used for star finding and centroiding; DAOPHOT is used for aperture
photometry; the astrometry.net plate-solving library is used for basic
astrometry, supplanted with more precise WCS that utilizes knowledge of the
optical train distortions. With these changes, DR10 includes many more

AAVSO Photometric All-Sky Survey (APASS), underway since 2010,
covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY
bandpasses. A northern and a southern site are used, each with twin ASA
20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square
degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for
all-sky solutions, with typical 0.02mag calibration errors on the bright
end.
Data Release 10 is a complete reprocessing of all 500K images taken with
the system, including hundreds of nights not part of DR9. Sextractor is
used for star finding and centroiding; DAOPHOT is used for aperture
photometry; the astrometry.net plate-solving library is used for basic
astrometry, supplanted with more precise WCS that utilizes knowledge of the
optical train distortions. With these changes, DR10 includes many more
stars than prior releases.

by merging data from NED, HyperLEDA, SIMBAD, and several databases

mostly to make them work as ADQL column names without resorting to

sdssdr16SDSS DR16 Selection This is a redacted version of the SDSS DR16 table prepared for VizieR
(V/154/sdss16). It is mainly here to facilitate local matches; for
original SDSS-related research, it is probably better to somewhere
else.
Over VizieR and SDSS, we are keeping most of the per-band values in
arrays to keep the column list manageable. Note that in ADQL, array
indexes are 1-based.
We are trying to orient our column names on SDSS but use underscores
instead of camel-casing (e.g. spec_obj_id instead of SpecObjID), since
mixed-case identifiers in SQL is asking for trouble.
To save space, we do not keep psf-based classifications, per-band
offsets, spectrum metadata, and USNO-related information in this
table. Let the operators know if you need any of that.sdssdr16.main This is a redacted version of the SDSS DR16 table prepared for VizieR

cns5updateThe Fifth Catalogue of Nearby Stars: Continuously Updated Version
(CNS5-updated)
The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most
volume-complete sample of stars in the solar neighbourhood. This is
a continuously-updated version of the published CNS5
(:bibcode:`2023A&A...670A..19G`).
The CNS5 is compiled based on trigonometric parallaxes from Gaia DR3 and
Hipparcos, and supplemented with astrometric data from Spitzer and
ground-based surveys carried out in the infrared. The CNS5 catalogue is
statistically complete down to 19.7 mag in G-band and 11.8 mag in W1-band
absolute magnitudes, corresponding to a spectral type of L8.
Continuous updates of observational data for nearby stars from all sources
were collected and evaluated. For all known stars in the 25 pc sphere
around the Sun, the best values of positions in space, velocities, and
magnitudes in different filters are presented.cns5update.main

fk6The Sixth Fundamental Catalogue (FK6) Parts I and III of the sixth fundamental catalog, a catalog of
high-precision astrometry for bright stars combining centuries of
ground-based observations as reflected in FK5 with HIPPARCOS
astrometry.
The result contains, in particular for the proper motions,
statistically significant improvements of the Hipparcos data und
represents a system of unprecedented accuracy for these 4150
fundamental stars. The typical mean error in pm is 0.35 mas/year for
878 basic stars, and 0.59 mas/year for the sample of the 3272

gcnsThe Gaia eDR3 Catalogue of Nearby Stars GCNS
This is a clean and well characterised catalogue of objects within 100pc of
the Sun from the Gaia early third data release. We characterise the
catalogue using the full data release, and comparisons to other catalogues
in literature and simulations. For all candidates (measured parallax <
8 mas), we calculate a distance probability function using Bayesian
procedures and mock catalogues for the prediction of the priors. For each
entry using a random forest classifier we attempt to remove sources with
spurious astrometric solutions.
This results in 331312 objects that should contain at least 92% of stars
within 100 pc at spectral type M9.
GCNS comes with several auxiliary tables, in particular lists of
resolved stellar systems, of known neary stars not found in eDR3 and
of candidates of Hyades and ComaBer cluster members.gcns.maineDR3 Gaia Catalogue of Nearby Stars (GCNS)This is the main catalogue. Additional resources include:
gcns.resolvedss (resolved stellar systems), gcns.missing_10mas

100 pc before), and gcns.hyacob (probable members of the Hyades and
the Coma Berenices open cluster).331312source_idGaia DR3 unique source identifier.

hsoyThe HSOY Catalog
HSOY is a catalog of 583'001'653 objects with precise astrometry based on
PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are
below 1 mas/yr for objects brighter than 10 mag, and about 5 mas/yr at the
faint end (about 20 mag). South of -30 degrees, astrometry is significantly
worse. HSOY also contains, where available, USNO-B, Gaia, and 2MASS
photometry. HSOY's positions and proper motions are given for epoch J2000.
The catalog becomes severely incomplete faintwards of 16 mag in the G-band.
The mean epochs are typically very close to Gaia's J2015.
HSOY still contains about 0.7% spurious close
"binaries" (non-matched stars) from the original USNO-B (marked with non-NULL
clone). Also, failed matches within Gaia DR1 contribute another 1.5% spurious
pairs (marked with non-NULL comp). In both cases, astrometry presumably is
sub-standard.

More information is available at http://dc.g-vo.org/hsoy.590000000ipixThe PPMXL object identifier, which in turn is the q3c ipix of the original USNO-B object; for HSOY, only (ipix, comp) is a unique identifier (primary key). The recommended identifier form is 'HSOY ipix.comp', where comp=0 for NULL comps. This is what the SCS generates.meta.id.crosslongindexedcompIf non-null this indicates that multiple Gaia objects matched the PPMXL object; this may indicate bona fide multiple stars, but more likely is due to failed matching of Gaia observations at different epochs. In both cases, proper motions must be used with care.

k2c9vstCoordinated microlensing survey observations with Kepler K2/C9 using
VST The Kepler satellite has observed the Galactic center in a campaign
lasting from April until the end of June 2016 (K2/C9). The main
objective of the 99 hours for the microlensing program 097.C-0261(A)
using the ESO VLT Survey Telescope (VST) was to monitor the superstamp
(i.e., the actually downloaded region of K2/C9) in service mode for
improving the event coverage and securing some color-information. Due
to weather conditions, the majority of images were taken in the red
band. These are part of the present release.
The exact pointing strategy was adjusted to cover the superstamp with
6 pointings and to contain as many microlensing events from earlier
seasons as possible. In addition, a two-point dither was requested to
reduce the impact of bad pixels and detector gaps. Consequently, some
events were getting more coverage and have been observed with
different CCDs. The large footprint of roughly 1 square degree and the
complementary weather conditions at Cerro Paranal have lead to the
coverage of 147 events (this resource's events table), but ~60 of
those were already at baseline.k2c9vst.eventsK2/C9 Microlensing Events The Kepler satellite has observed the Galactic center in a campaign

k2c9vst.timeseries The Kepler satellite has observed the Galactic center in a campaign
lasting from April until the end of June 2016 (K2/C9). The main
objective of the 99 hours for the microlensing program 097.C-0261(A)
using the ESO VLT Survey Telescope (VST) was to monitor the superstamp
(i.e., the actually downloaded region of K2/C9) in service mode for
improving the event coverage and securing some color-information. Due
to weather conditions, the majority of images were taken in the red
band. These are part of the present release.
The exact pointing strategy was adjusted to cover the superstamp with
6 pointings and to contain as many microlensing events from earlier
seasons as possible. In addition, a two-point dither was requested to
reduce the impact of bad pixels and detector gaps. Consequently, some
events were getting more coverage and have been observed with
different CCDs. The large footprint of roughly 1 square degree and the
complementary weather conditions at Cerro Paranal have lead to the
coverage of 147 events (this resource's events table), but ~60 of
those were already at baseline.119accrefAccess key for the datameta.ref.url;meta.datasetssa:Access.ReferencecharindexednullableownerOwner of the datacharnullableembargoDate the data will become/became publicacharnullablemimeMIME type of the file servedmeta.code.mimessa:Access.FormatcharnullableaccsizeSize of the data in bytesbytessa:Access.Sizelongnullablessa_dstitleA compact and descriptive designation of the dataset.meta.title;meta.datasetssa:DataID.Titlecharssa_creatordidDataset identifier assigned by the creatormeta.idssa:DataID.CreatorDIDcharnullablessa_pubdidDataset identifier assigned by the publishermeta.ref.ivoidssa:Curation.PublisherDIDcharindexednullablessa_cdateProcessing/Creation datetime;meta.datasetssa:DataID.Datecharnullablessa_pdateDate last published.ssa:Curation.Datecharnullablessa_bandpassBandpass (i.e., rough spectral location) of this dataset; this should be the most appropriate term from the vocabulary http://www.ivoa.net/rdf/messenger.instr.bandpassssa:DataID.Bandpasscharnullablessa_cversionCreator assigned version for this dataset (will be incremented when this particular item is changed).meta.version;meta.datasetssa:DataID.Versioncharnullablessa_targnameCommon name of object observed.meta.id;srcssa:Target.Namecharindexedssa_targclassObject class (star, QSO,...; use Simbad object classification http://simbad.u-strasbg.fr/simbad/sim-display?data=otypes if at all possible)src.classssa:Target.Classcharnullablessa_redshiftRedshift of target objectsrc.redshiftssa:Target.Redshiftfloatnullablessa_targetposEquatorial (ICRS) position of the target object.pos.eq;srcssa:Target.pos.spointdoublenullablessa_snrSignal-to-noise ratio estimated for this datasetstat.snrssa:Derived.SNRfloatnullablessa_locationICRS location of aperture centerdegpos.eqssa:Char.SpatialAxis.Coverage.Location.Valuedoubleindexednullablessa_apertureAngular diameter of aperturedegphys.angSize;instr.fovssa:Char.SpatialAxis.Coverage.Bounds.Extentfloatnullablessa_dateobsMidpoint of exposure (MJD)dtime.epochssa:Char.TimeAxis.Coverage.Location.Valuedoublenullablessa_timeextExposure durationstime.durationssa:Char.TimeAxis.Coverage.Bounds.Extentfloatnullablessa_specmidMidpoint of region covered in this datasetminstr.bandpassssa:Char.SpectralAxis.Coverage.Location.Valuefloatnullablessa_specextWidth of the spectrumminstr.bandwidthssa:Char.SpectralAxis.Coverage.Bounds.Extentfloatnullablessa_specstartLower value of spectral coordinatemem.wl;stat.minssa:Char.SpectralAxis.Coverage.Bounds.Startfloatnullablessa_specendUpper value of spectral coordinatemem.wl;stat.maxssa:Char.SpectralAxis.Coverage.Bounds.Stopfloatnullablessa_lengthNumber of points in the spectrumssa:Dataset.Lengthintnullablessa_dstypeType of data (spectrum, time series, etc)ssa:Dataset.Typecharnullablessa_publisherPublisher of the datasets included here.meta.curationssa:Curation.Publishercharnullablessa_creatorCreator of the datasets included here.ssa:DataID.CreatorunicodeCharnullablessa_collectionA short handle naming the collection this spectrum belongs to.ssa:DataID.Collectioncharnullablessa_instrumentInstrument or code used to produce these datasetsmeta.id;instrssa:DataID.Instrumentcharnullablessa_datasourceMethod of generation for the data (one of survey, pointed, theory, custom, artificial).ssa:DataID.DataSourcecharnullablessa_creationtypeProcess used to produce the data (archival, cutout, filtered, mosaic, projection, spectralExtraction, or catalogExtraction)ssa:DataID.CreationTypecharnullablessa_referenceURL or bibcode of a publication describing this data.meta.bib.bibcodessa:Curation.Referencecharnullablessa_fluxstaterrorStatistical error in fluxadustat.error;phot.flux.density;emssa:Char.FluxAxis.Accuracy.StatErrorfloatnullablessa_fluxsyserrorSystematic error in fluxadustat.error.sys;phot.flux.density;emssa:Char.FluxAxis.Accuracy.SysErrorfloatnullablessa_fluxcalibType of flux calibration (ABSOLUTE, CALIBRATED, RELATIVE, NORMALIZED, or UNCALIBRATED).ssa:Char.FluxAxis.Calibrationcharnullablessa_binsizeBin size in wavelengthmem.wl;spect.binSizessa:Char.SpectralAxis.Accuracy.BinSizefloatnullablessa_spectstaterrorStatistical error in wavelengthmstat.error;emssa:Char.SpectralAxis.Accuracy.StatErrorfloatnullablessa_spectsyserrorSystematic error in wavelengthmstat.error.sys;emssa:Char.SpectralAxis.Accuracy.SysErrorfloatnullablessa_speccalibType of wavelength calibrationmeta.code.qualssa:Char.SpectralAxis.Calibrationcharnullablessa_specresResolution (in meters of wavelength) on the spectral axismspect.resolution;em.wlssa:Char.SpectralAxis.Resolutionfloatnullablet_min_mjd(Approximate) earliest timestamp in dataset.dtime.start;obsts:time.startdoubleindexednullablet_max_mjd(Approximate) latest timestamp in dataset.dtime.end;obsts:time.enddoubleindexednullablet_0Time of largest magnification estimated from a fit assuming a gravitational lens event of pointlike source and lens.dtime.duration;stat.fitdoublenullable

mwscGlobal Survey of Star Clusters in the Milky Way MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found
in the 2MAst (2MASS with Astrometry) catalogue. The target list was
compiled on the basis of present-day lists of open, globular and
candidate clusters. For confirmed clusters we determined a homogeneous
set of astrophysical parameters such as membership, angular radii of
the main morphological parts, mean cluster proper motions, distances,
reddenings, ages, tidal parameters, and sometimes radial velocities.mwsc.mainA list of milky way stellar cluster candidates and objects, together

on V-band imaging data acquired with the William Herschel Telescope.
Additionally, we used archival Subaru multiband imaging data in order
to measure aperture colors and to perform a morphological
classification. The catalog reaches its 50 per cent completeness limit
at an absolute V-band luminosity of -12 mag and a V-band surface
brightness of 26 mag arcsec^-2 .
In addition to the published table, this service also contains cutout

This service publishes plate scans of the Palomar-Leiden Troian
surveys conducted between 1960 and 1977. The surveys led to the
discovery of more than 2,000 asteroids (1,800 with orbital information),
with another 2,400 asteroids, including 19 Trojans, found after further
analysis of the plates.
Note that because of the large size of the plates, in this service each
original plate is contained in two parts, marked with "_1" and "_2",
respectively. The central parts

A 3D map of interstellar dust reddening, covering three
quarters of the sky (declinations greater than -30 degrees) out to a
distance of several kiloparsecs. The map is based on high-quality stellar
photometry of 800 million stars from Pan-STARRS 1 and 2MASS.
The map is available for five HEALPix levels (6 through 10), published
here as separate tables, map6 through map10. A union of the coverage is
provided as map_union. Use its coverage column to match against other
tables.

rave.mainThe RAVE object catalog of radial velocities, surface gravities, and
chemical parameters for about 500000 stars, data release 5. We have
removed almost all fields originating from crossmatches (as this is
intended for use within our TAP service, where users can do the
crossmatches themselves). Also, some obviously buggy columns (e.g.,
footprint_flag) were dropped.
Note that columns with names ending in _k originate from the stellar
parameters pipeline, those with names ending in _c come from the
chemical pipeline.

sasmiralaSasmirala: Subarcsecond mid-infrared atlas of local AGN The Subarcsecond mid-infrared (MIR) atlas of local active galactic
nuclei (AGN) is a collection of all available N- and Q-band images
obtained at ground-based 8-meter class telescopes with public archives
(Gemini/Michelle, Gemini/T-ReCS, Subaru/COMICS, and VLT/VISIR). It
includes in total 895 images, of which 60% are perviously unpublished.
These correspond to 253 local AGN with a median redshift of 0.016. The
atlas contains the uniformly processed and calibrated images and
nuclear photometry obtained through Gauss and PSF fitting for all
objects and filters. This also includes measurements of the nuclear
extensions. In addition, the classifications of extended emission (if
present) and derived nuclear monochromatic 12 and 18 micron continuum
fluxes are available. Finally, flux ratios with the circumnuclear MIR
emission (measured by Spitzer) and total MIR emission of the galaxy
(measured by IRAS) are presented.sasmirala.objectsSasmirala Basic Object PropertiesBasic object properties and nuclear 12 and 18 micron continuum

wfpdbWide-Field Plate Database WFPDB
The Wide-Field Plate Database (WFPDB_) contains the descriptive information
for the astronomical wide-field (>1°) photographic observations stored in
numerous archives all over the world. The total number of these
observations, obtained since the end of the 19th century with more
then 200 instruments (telescopes) is about 2 550 000 from 509 archives.
The WFPDB is continually being updated, providing currently access to the
information for about 640 000 plates from 117 plate archives (30% of the
estimated total number of wide-field plates)

applauseAPPLAUSE DR3 Plate Scans APPLAUSE DR3 contains images and metadata from 24 plate collections
in Hamburg, Bamberg, Potsdam, Tautenburg and Tartu, a total of 101138
scans of 70276 photographic plates. The present table contains
metadata records for singly exposed plates with astrometric solutions
in APPLAUSE (about 44000). It is mainly intended as a basis for
publishing suitable APPLAUSE plates in the Obscore schema through the
TAP service in GAVO's Heidelberg Data Center.

glotsGloTS, the Global TAP Schema
The global TAP schema collects information on
tables and columns from known TAP servers. This facilitates locating
queriable data by physics (via UCD) or keywords (via description).
Note that this shouldn't really be necessary as all information
present here should be exposed through Registry records. However,
in reality data providers currently are much more liable to give
column metadata in their tap_schema than in their Registry records.
Hence, for the time being, we maintain this service by harvesting

gdr2distEstimated distances to 1.33 billion stars in Gaia DR2
This catalogue provides distances estimates (and uncertainties therein)
for 1.33 billion stars over the whole sky brighter than about G=20.7.
These have been estimated using the parallaxes (and their uncertainties)
from Gaia DR2. A Bayesian procedure was used involving a prior
with a single parameter L(l,b), which varies smoothly with Galactic
longitude and latitude according to a Galaxy model. The posterior is
summarized with a point estimate (usually the mode) and a confidence
interval (usually the 68% highest density interval). The estimation
procedure is described in detail in the `accompanying paper`_,
which also analyses the catalogue content.

Galaxia (a tool to sample stars from a Besancon-like Milky Way model),
3d dust extinction maps and the latest PARSEC Isochrones. It is
mimicking the Gaia DR2 data model and an apparent magnitude limit of
g=20,7. Extinctions and photometry in different bands have also been
included in a supplementary table as well as uncertainty estimates

gps1The Gaia-PS1-SDSS (GPS1) Proper Motion Catalog
This catalog combines Gaia DR1, Pan-STARRS 1, SDSS and 2MASS astrometry
to compute proper motions for 350 million sources across three-fourths of
the sky down to a magnitude of mr≈20. Positions of galaxies from Pan-STARRS 1
are used to build a reference frame for PS1, SDSS, and 2MASS data.
Gaia DR1 is adapted to that reference frame by exploiting that locally,
proper motions are linear.
GPS1 has a characteristic systematic error of less than 0.3 mas/yr, and
a typical precision of 1.5−2.0 mas/yr. The proper motions have been
validated using galaxies, open clusters, distant giant stars and QSOs. In
comparison with other published faint proper motion catalogs, GPS1's
systematic error (<0.3 mas/yr) is about 10 times better than that of PPMXL
and UCAC4 (>2.0 mas/yr). Similarly, its precision (~1.5 mas/yr) is
an improvement by ∼ 4 times relative to PPMXL and UCAC4 (∼6.0 mas/yr).
For QSOs, the precision of GPS1 is found to be worse (∼2.0−3.0 mas/yr),
possibly due to their particular differential chromatic refraction (DCR).gps1.mainGPS1 main table with some deviations from the published paper. In
particular note that Gaia and Pan-STARRS1 photometry results from
blind crossmatching; see d_g and d_ps1 fields for the offsets in the

onebigb1BIGB: First Brazil-ICRANet Gamma-Ray Blazar Catalogue
This catalog presents the 1-100 GeV spectral energy distribution (SED)
for a population of 148 high-synchrotron-peaked blazars (HSPs) recently
detected with Fermi-LAT as part of the
First Brazil-ICRANet Gamma-ray Blazar catalogue (1BIGB).
A series of two works describe details on the broadband analysis:
:bibcode:`2017A&A...598A.134A`, and the calculation of the
gamma-ray SEDs :bibcode:`2018MNRAS.480.2165A`.
The 1BIGB sample was originally selected from an excess signal in the
0.3-500 GeV band The flux estimates presented here are derived considering
PASS8 data, integrating over more than 9 years of Fermi-LAT observations. The
full broadband fit between 0.3-500 GeV presented in paper 1 for all sources
was reevaluated in paper 2, updating the power-law parameters with currentlyonebigb.measurementsA table of raw measurement points. See the seds table for combined

plc2Astrometric Microlensing Events Predicted from Gaia DR2 From the Gaia DR2 catalogue we predict astrometric microlensing
events by foreground stars with high proper motion (µ_tot >150mas/yr)
passing a background source in the next decades. Using Gaia DR2
photometry we determine an approximate mass of the lens, which we use
to calculate the expected microlensing effects. This yields 3914
microlensing events by 2875 different lenses between 2010 and 2065
with expected shifts larger than 0.1 mas between the lensed and
unlensed positions of the source. 513 of those are expected to happen
between 2014.5 - 2026.5 and might be measured by Gaia. For 127 events
we also expect a magnification between 1 mmag and 3 mag.plc2.dataThe final candidate table for astrometric microlensing events
predicted from Gaia DR2. This has estimates of minimal distances,
epochs, etc. Columns prefixed with lens_ are for the lens, columns
prefixed with ob_ are for the lensed object.3914event_idUnique identifier of this event.

ucac4The fourth U.S. Naval Observatory CCD Astrograph Catalog (UCAC4) UCAC4 is a compiled, all-sky star catalog covering mainly the 8 to 16
magnitude range in a single bandpass between V and R.
Positional errors are about 15 to 20 mas for stars in the 10 to 14 mag
range. Proper motions have been derived for most of the about 113
million stars utilizing about 140 other star catalogs with significant
epoch difference to the UCAC CCD observations. These data are
supplemented by 2MASS photometric data for about 110 million stars and
5-band (B,V,g,r,i) photometry from the APASS (AAVSO Photometric
All-Sky Survey) for over 50 million stars. UCAC4 also contains error
estimates and various flags. All bright stars not observed with
the astrograph have been added to UCAC4 from a set of Hipparcos and
Tycho-2 stars. Thus UCAC4 should be complete from the brightest stars
to about R=16, with the source of data indicated in flags.ucac4.main UCAC4 is a compiled, all-sky star catalog covering mainly the 8 to 16

ucac5The fifth U.S. Naval Observatory CCD Astrograph Catalog (UCAC5) New astrometric reductions of the US Naval Observatory CCD Astrograph
Catalog (UCAC) all-sky observations were performed from first
principles using the TGAS stars in the 8 to 11 magnitude range as
reference star catalog. Significant improvements in the astrometric
solutions were obtained and the UCAC5 catalog of mean positions at a
mean epoch near 2001 was generated. By combining UCAC5 with Gaia DR1
data new proper motions on the Gaia coordinate system for over 107
million stars were obtained with typical accuracies of 1 to 2 mas/yr
(R = 11 to 15 mag), and about 5 mas/yr at 16th mag. Proper motions of
most TGAS stars are improved over their Gaia data and the precision
level of TGAS proper motions is extended to many millions more,
fainter stars.
The database table uses actual NULLs for missing photometry, and all
angular coordinates have been homogenised to degrees.ucac5.main New astrometric reductions of the US Naval Observatory CCD Astrograph

URAT1 star catalog
URAT1 is an observational catalog at a mean epoch between 2012.3 and
2014.6; ot covers the magnitude range 3 to 18.5 in R-band, with a
positional precision of 5 to 40 mas. It covers most of the northern
hemisphere and some areas down to -24.8° in declination.
In the GAVO data center, we left out all columns originating from
cross matches with other catalogs; on-the fly crossmatches can be done
in our TAP service.urat1.main

zcosmoszCOSMOS Bright Spectroscopic Observations DR2
The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over
five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies
selected to have Iab < 22.5 across the full 1.7 deg2 of the COSMOS field.
This part, "zCOSMOS-bright", was designed to yield a high and fairly uniform
sampling rate (about 70%), with a high success rate in measuring redshifts
(approaching 100% at 0.5 < z < 0.8), and with sufficient
velocity accuracy
(about 100 km/s) to efficiently map the environments of galaxies down to the
scale of galaxy groups out to redshifts z ~ 1.zcosmos.data
