2.1.5 lens_catalogue_name

This table provides the list of input catalogues that have been used to select any given source that was analysed by the Gravitational Lens module and published in the lens candidate table.
Each source may have been cross-matched to more than one catalogue and therefore can have several entries in the table.
For the FPR, the catalogues considered for this selection are mostly external, although sources identified by DPAC based on the classification performed by other processing have also been included here.
Each catalogue is assigned a catalogue_id. For the FPR the following applies:

• •

  1: Ducourant+2022 Ducourant et al. (2023)

• •

  2: Gravitational Lens data base (Ducourant+2023): Ducourant (2023)

• •

  3: Gravitational Lens candidates (Krone-Martins+2023): Gaia Collaboration, Krone-Martins, A., et al. (2023b)

• •

  4: Milliquas 7.5b Flesch (2021)

• •

  5: Milliquas 7.5 Flesch (2021)

• •

  6: Milliquas 7.4d Flesch (2021)

• •

  7: Milliquas 7.4c Flesch (2021)

• •

  8: Milliquas 7.1b Flesch (2019)

• •

  9: Milliquas 7.0 Flesch (2019)

• •

  10: Milliquas 6.4 Flesch (2019)

• •

  11: Assef R90 Assef et al. (2018)

• •

  12: Shu+2019 Shu et al. (2019)

• •

  13: Assef C75 Assef et al. (2018)

• •

  14: Sergei Klioner, private communication, 2022.

Further details on these catalogues are given in Ducourant+2023.

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 : Unique source identifier (unique within a particular Data Release) (long)

A unique single numerical identifier of the source obtained from the Gaia DR3 main source catalogue (for a detailed description see gaiadr3.gaia_source.source_id).

catalogue_id : The unique identifier for the catalogue(s) used to select the sources in the gravitational lenses analysis (byte)

Each catalogue used to select the sources analysed by the gravitational lens module is assigned a unique ID. The corresponding catalogues are listed in the description of the lens_catalogue_name table, and further details are given in the FPR documentation.
