Nomenclature: Gaia EDR3 NNNNNNNNNNNNNNNNNNN N=1811709771

CDS comments: See also Gaia DR3 Part 1 Main Source : 2022yCat.1355....0G. 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 and DR3; on another hand the G magnitudes have been slighty corrected in Gaia DR3, and Gaia DR3 published about 23 million radial velocities. The radial velocities in Gaia EDR3 are those of Gaia DR2.
