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.

  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.
