Information on resource 'Gaia Data Release 1 (DR1)'
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.
We do not publish Gaia DR1 data here any more. If you actually
need DR1 data, refer to the full Gaia mirrors, for instance
the one at ARI. Otherwise, please use more recent data releases,
for instance eDR3.
Tables defined within this resource descriptor
- gaia.dr1 – queryable through TAP and ADQL
This table, corresponding to gaia_source of the full DR1, contains
the 1.15 billion objects reliably detected in the first 14 months of
Gaia observations. It essentially consists of high-precision positions
and magnitudes. The TGAS subset (about 2 million objects observed by
both Gaia and Hipparcos) has proper motions and parallaxes. Users are
advised to beware strong correlations between the astrometric
parameters present for some of the less densely observed objects and
the inhomogeneous coverage in this first data release (solution id:
1635378410781933568).
