Information on resource 'Selections from Gaia Data Release 3 (DR3)'
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 gdr3mock,
gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.

Tables defined within this resource descriptor
- gaia.dr3lite – queryable through TAP and ADQL
This is gaia_source from the Gaia Data Release 3, stripped to just
enough columns to enable basic science (but therefore a bit faster and
simpler to deal with than the full gaia_source table).
Note that on this server, there is also The gedr3dist.main, which
gives distances computed by Bailer-Jones et al. Use these in
preference to working with the raw parallaxes.
This server also carries the gedr3mock schema containing a simulation
of gaia_source based on a state-of-the-art galaxy model, computed by
Rybizki et al.
The full DR3 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).
- gaia.edr3lite – queryable through TAP and ADQL
This is a “light” version of the full Gaia DR3 gaia_source table. It
is just a view copying gaia.dr3lite, which should preferentially be
used in new queries. This table is being kept around in order to keep
legacy queries from breaking unnecessarily. However, it is actually
DR3 data rather than eDR3. The minute differences did not seem to
warrant keeping two copies of the relatively massive data around.
