QSO Catalogue name (gaiadr3.qso_catalogue_name)
The table has 2722093 rows, 3 columns.
This table provides the list of input catalogues that have been used to select any given source for which morphological analysis parameters are provided in table
qso_candidates.Each source may have been cross-matched to more than one catalogue and therefore can have several entries in the table. For DR3, 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 DR3 the following applies:
- 1: GaiaVariQso2018 (internal DPAC classification based on photometry variability)
- 2: ICRF2
- 3: SDSS-DR12Q
- 4: LQAC3
- 5: Half Million Quasars
- 6: Secrest+2015
- 7: Assef+2018_C75
