20.2.2 astrophysical_parameters_supp

This table contains additional parameters from the Apsis processing chain, compared to the main table astrophysical_parameters (see Chapter 11), from modules that produce more than one result for a parameter. It contains (1) the individual library results from GSP-Phot (see Section 11.3.3), (2) FLAME results from processing GSP-Spec parameters given in the astrophysical_parameters table (see Section 11.3.6), and (3) results from the GSP-Spec ANN algorithm (see Section 11.3.4).

Columns description:

solution_id : Solution Identifier (long)

All Gaia data processed by the Data Processing and Analysis Consortium comes tagged with a solution identifier. This is a numeric field attached to each table row that can be used to unequivocally identify the version of all the subsystems that were used in the generation of the data as well as the input data used. It is mainly for internal DPAC use but is included in the published data releases to enable end users to examine the provenance of processed data products. To decode a given solution ID visit https://gaia.esac.esa.int/decoder/solnDecoder.jsp

source_id : Source Identifier (long)

A unique single numerical identifier of the source obtained from gaia_source (for a detailed description see gaia_source.source_id).
