- Description:
- 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).

- Description:
- This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes). Other Gaia-related data is found in, among others, the gdr2dist, gdr3mock, gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.

- Description:
- This service exposes about 0.5 million light curves of stars classified as variable by the Gaia analysis system through the VO SSAP protocol. The lightcurves are published per-band and are also available through obscore.

- Description:
- 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 distances computed by Bailer-Jones et al (:bibcode:`2018AJ....156...58B`). If in doubt, use these instead of the parallaxes provided here.
