Gaia Universe Model (gaiaedr3.gaia_universe_model)
The table has 4378665080 rows, 43 columns.
Description
Table of simulated galactic stars according to the Gaia Universal Model Simulation (GUMS). True values of the intrinsic simulated quantities (astrometry, photometry and physical parameters) for the sources generated by GOG using the Universe Model are given. No errors are added.
