This service provides Gaia data (currently DR1, DR2 and EDR3), with full-sky catalogues of high-precision positions down to about 20 mag, as a mirror of the original ESA archive with extra features (e.g., tables and column metadata).
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).
