Table information for 'gedr3mock.generated_data'


Table Description: This contains the data actually generated. Users probably want to use the gdr2mock.main table that (fairly well) follows the Gaia DR2 data model.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This catalogue is a simulation of the Gaia EDR3 stellar content using Galaxia (a tool to sample stars from a Besancon-like Milky Way model), 3d dust extinction maps and the latest PARSEC Isochrones. It is mimicking the Gaia DR2 data model and an apparent magnitude limit of G=20,7. Extinctions and photometry in different bands have also been included in a supplementary table as well as uncertainty estimates using scaled GDR2 errors. Additional magnitude limit per HEALpix maps are provided, based on the mode in the magnitude distribution of Gaia DR2 data.

The last digits of the source_id are reserved for a running number that serves as a unique identifier per HEALPix cell.
