The early third release of the Gaia catalog (Gaia EDR3) includes data for approximately 1.8 billion stars.  The limiting magnitude is around 21.  This catalog offers astrometric precision of 0.002" at the 20 magnitude level.

The offline variant, "GRAPPA", was developed by Marc Serrau.  Please also include the following acknowledgements if using the catalog in a published paper:
