Tycho-Gaia Astrometric Solution (TGAS) Catalog

This table is a subset of gaia_source comprising those stars in the Hipparcos and Tycho-2 Catalogues for which a full 5-parameter astrometric solution has been possible in Gaia Data Release 1. Total number of records is 2,057,050.

Please refer to the Gaia project page for Gaia itself.
