Information on Service 'BGDS Mean Photometry Cone Search'

[Use this service from your browser]

Further access options are discussed below

Extracted sources from the Bochum Galactic Disk Survey. We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also, sources sitting in the regions imaged in multiple fields have not been matched even within one band. In i and r, BGDS light curves are available. See related services for details.

For a list of all services and tables belonging to this service's resource, see Information on resource 'BGDS time series'

Overview

You can access this service using:

This service is published as follows:

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

MAXREC Match limit Maximum number of records returned. Pass 0 to retrieve service parameters. N/A N/A
mean_mag 〈mag〉 Mean magnitude in band given in phot_band. mag phot.mag;stat.mean
RA Alpha (ICRS) Right Ascension (ICRS decimal) deg pos.eq.ra
RESPONSEFORMAT Output Format File format requested for output. N/A meta.code.mime
SR Search Radius Search radius deg N/A
VERB Verbosity Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns. N/A N/A

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

NameTable Head DescriptionUnitUCD
_r Dist. Distance to cone center deg pos.distance
amp Amplitude Difference between brightest and weakest observation. mag arith.diff;phot.mag
band_name Filter The band the mean photometry is given for. N/A meta.id;instr.filter
dec Dec ICRS declination for this object. N/A pos.eq.dec;meta.main
err_flux Err〈flux〉 Error in mean flux in this band mJy stat.error;phot.flux
err_mag Err〈mag〉 Error in mean magnitude in this band mag stat.error;phot.mag

mean_mag 〈mag〉 Mean magnitude in band given in phot_band. mag phot.mag;stat.mean
obs_id Obs_id Main identifier of this observation (a single object may have multiple observations in different bands and fields) N/A meta.id;meta.main
ra Ra ICRS right ascension for this object. N/A pos.eq.ra;meta.main

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.

NameTable Head DescriptionUnitUCD Verb. Level
band_name Filter The band the mean photometry is given for. N/A meta.id;instr.filter 1
obs_id Obs_id Main identifier of this observation (a single object may have multiple observations in different bands and fields) N/A meta.id;meta.main 1
ra Ra ICRS right ascension for this object. N/A pos.eq.ra;meta.main 1
dec Dec ICRS declination for this object. N/A pos.eq.dec;meta.main 1
mean_mag 〈mag〉 Mean magnitude in band given in phot_band. mag phot.mag;stat.mean 5

_r Dist. Distance to cone center deg pos.distance 10
err_mag Err〈mag〉 Error in mean magnitude in this band mag stat.error;phot.mag 15
