Table information for 'gaiadr3_eb.lightcurves'

General

Table Description: This table contains all rows of Gaia DR3 epoch photometry for eclipsing binaries. The data were retrieved via the original Gaia DR3 DataLink service.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

This schema contains data re-published from the official Gaia DR3 TAP services (e.g., ivo://uni-heidelberg.de/gaia/tap). It provides simplified access to data related to eclipsing binary stars, including epoch photometry and basic parameters from the gaiadr3.gaia_source and gaiadr3.vari_eclipsing_binary tables. Timeseries are available via SSAP and DataLink.

For a list of all services and tables belonging to this table's resource, see Information on resource 'Gaia DR3 eclipsing binaries'

Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2023A&A...674A...1G (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

@MISC{vo:gaiadr3_eb_light,

  title={Gaia DR3 epoch photometry for eclipsing binaries},
  author={{GAIA} Collaboration},
  url={https://skvo.science.upjs.sk/tableinfo/gaiadr3_eb.lightcurves},
  howpublished={{VO} resource provided by the Pavol Jozef Šafárik University Archive}

If you use public Gaia DR3 data in a paper, please take note of ESAC's guide on how to acknowledge and cite it.

Columns

Sorted alphabetically. [Sort by DB column index]

NameTable Head DescriptionUnitUCD
band Photometric Band Photometric band. Values: G (per-transit combined SM-AF flux), BP (blue photometer integrated flux) and RP (red photometer integrated flux) N/A instr.bandpass
flux Flux Band flux value for the transit. For G band, it is a combination of individual SM-AF CCD fluxes. For BP and RP bands, it is an integrated CCD flux. s**-1 phot.flux;em.opt;stat.mean
flux_error Flux error Flux error. If the flux has been rejected or is unavailable, this error will be set to null. s**-1 stat.error;phot.flux;em.opt
obs_time Observation Time observation time converted to mjd ??? Different times are defined for each band. For G, it is the field-of-view transit averaged observation time. For BP and RP, it is the observation time of the BP CCD transit. The units are Barycentric JD (in TCB) in days -2,455,197.5, computed as follows. First the observation time is converted from On-board Mission Time (OBMT) into Julian date in TCB (Temps Coordonnee Barycentrique). Next a correction is applied for the light-travel time to the Solar system barycentre, resulting in Barycentric Julian Date (BJD). Finally, an offset of 2,455,197.5 days is applied (corresponding to a reference time $T_0$ at 2010-01-01T00:00:00) to have a conveniently small numerical value. Although the centroiding time accuracy of the individual CCD observations is (much) below 1~ms (e.g. in BP and RP), the G band observation time is averaged over typically 9 CCD observations taken in a time range of about 44sec. d time.epoch
