Table information for 'gdr2mock.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 not available for ADQL queries and through the TAP endpoint.

Resource Description: This catalogue is a simulation of the Gaia DR2 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 a scaled nominal error model.

source_id ID Healpix number using Nside = 4096 with the nested scheme on equatorial coordinates times 2^35. The last digits of the source_id are reserved for a running number that serves as a unique identifier per HEALPix cell. This is formed in accordance with Gaia's source_id definition, but of course mock objects have no relation to any Gaia objects that may have an identical source_id. N/A;meta.main
