Information on resource 'Gaia Data Release 1 (DR1)'
The Gaia satellite takes high-precision astrometry of a large number
of astronomical objects. This data collection mirrors the larger
tables released by DPAC.

- gaia.dr1 – queriable 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).
