Gaia Source Simulation (gaiaedr3.gaia_source_simulation)

The table has 1644232695 rows, 38 columns.

Description

Table of sources realised according to the Gaia Object Generator (GOG) simulation. Observed attributes are given with simulated observational uncertainties.This table contains the output of GOG. The values are obtained after adding the corresponding uncertainty (based on the error models) to the true values in table GaiaUniverseModel. Both the values and the uncertainties are provided.
