Information on resource 'BGDS DR2 time series'

Services defined within this resource descriptor

• BGDS DR2 Mean Photometry Cone Search

  Extracted sources from the Bochum Galactic Disk Survey. We provide median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII, NB, Halpha and SII for particular fields. 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. BGDS light curves are available in i and r for all fields and partially in U, B, V, z, OIII, NB, Halpha and SII in a separate SSAP service and via TAP.

• BGDS DR2 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 DR2 time series datalink

  This service produces time series datasets for Bochum Galactic Disk Survey lightcurves.

• Bochum Galactic Disk Survey (BGDS) DR2 light curves

  This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey DR2; 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.

• Bochum Galactic Disk Survey (BGDS) DR2 light curves browser service

Tables defined within this resource descriptor

• bgds2.lc_allbands – queryable through TAP and ADQL

  BGDS DR2 lightcurves as arrays. This is available only for objects with sufficient coverage. To obtain positions and mean photometry, join with the corresponding phot_all or, better, with the appropriate phot_(band) table. Note that mags is mixed-band; obtain the filter used from the filter column.

• bgds2.phot_all – queryable through TAP and ADQL

  A collection of all BGDS photometry points. Note that the flux and mag columns are rather weird in that their bands vary from row to row.

• bgds2.phot_b – queryable through TAP and ADQL

  BGDS median photometry in the Johnson B band. This is available for all objects found in the fields observed.

• bgds2.phot_ha – queryable through TAP and ADQL

  BGDS median photometry in the Astrodon Halpha band. This is available for all objects found in the fields observed.

• bgds2.phot_i – queryable through TAP and ADQL

  BGDS median photometry in the SDSS i' band. This is available for all objects found in the fields observed.

• bgds2.phot_nb – queryable through TAP and ADQL

  BGDS median photometry in the Astrodon NB band. This is available for all objects found in the fields observed.

• bgds2.phot_oiii – queryable through TAP and ADQL

  BGDS median photometry in the Astrodon OIII band. This is available for all objects found in the fields observed.

• bgds2.phot_r – queryable through TAP and ADQL

  BGDS median photometry in the SDSS r' band. This is available for all objects found in the fields observed.

• bgds2.phot_sii – queryable through TAP and ADQL

  BGDS median photometry in the Astrodon SII band. This is available for all objects found in the fields observed.

• bgds2.phot_u – queryable through TAP and ADQL

  BGDS median photometry in the Johnson U band. This is available for all objects found in the fields observed.

• bgds2.phot_v – queryable through TAP and ADQL

  BGDS median photometry in the Johnson V band. This is available for all objects found in the fields observed.

• bgds2.phot_z – queryable through TAP and ADQL

  BGDS median photometry in the SDSS z' band. This is available for all objects found in the fields observed.

• bgds2.ssa_time_series

  This table contains metadata about the photometric time series from BGDS in IVOA SSA format. The actual data is available through a datalink service or in the lc_allband table.
