CDS comments: Two special operations of cross-identification between the content of SIMBAD and Gaia E/DR3 have been performed in February and May 2022, involving about 7 million objects. The operation was limited to objects with a good astrometry (coordinates with a quality D and E excluded). Note that the identifiers and astrometric parameters (coordinates, proper motions, parallaxe) are the same in Gaia EDR3 (2020yCat.1350....0G) and DR3; on another hand the G magnitudes have been slighty corrected in Gaia DR3, and Gaia DR3 published about 23 million radial velocities. See also 2022yCat.1358....0G and 2022yCat.1357....0G to know the status of Variable and Non-single stars in SIMBAD.
