Information on resource 'BGDS 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.
Services defined within this resource descriptor
- BGDS Mean Photometry Cone Search
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.
- BGDS time series
A service returning PNG thumbnails for time series. It takes the obs
id for which to generate a preview from the remaining fragments.
- BGDS time series datalink
This service produces time series datasets for Bochum Galactic Disk
Survey lightcurves.
- Bochum Galactic Disk Survey (BGDS) light curves
This service exposes the light curves of stars produced by the Bochum
Galactic Disk Survey; several million light curves are provided in the
SDSS i and r bands. The lightcurves are published per-band and are
also available through obscore.

Tables defined within this resource descriptor
- bgds.phot_all – queryable through TAP and ADQL
All mean photometry of bgds in one table. It may be simpler to write
queries against the split-band tables phot_band. Measurements in
different fields and bands have not been merged, as that procedure is
too error-prone in crowded milky way regions.
- bgds.phot_b
BGDS wideband photometry in the Johnson B band. A union of all the
BGDS measurements is available in phot_all.
- bgds.phot_i
BGDS mean broadband photometry and lightcurves measurements in the
SDSS i band. All BGDS broadband mean photometry is available in
phot_all.
- bgds.phot_r
BGDS mean broadband photometry and lightcurves measurements in the
SDSS r band. All BGDS broadband mean photometry is available in
phot_all.
- bgds.phot_u
BGDS wideband photometry in the Johnson U band. A union of all the
BGDS measurements is available in phot_all.
- bgds.phot_v
BGDS wideband photometry in the Johnson V band. A union of all the
BGDS measurements is available in phot_all.
- bgds.phot_z
BGDS wideband photometry in the SDSS z band. A union of all the BGDS
measurements is available in phot_all.
- bgds.ssa_time_series – queryable through TAP and ADQL
This table contains about metadata about the photometric time series
from BGDS in IVOA SSA format. The actual data is available through a
datalink service or in the phot_i and phot_r tables.
