Gaia CRF3 cross-matches (gaiadr3.gaia_crf3_xm)

The table has 1614173 rows, 37 columns.

Description

This table contains the full cross-match information for the Gaia-CRF3 sources. The Gaia-CRF3 sources were selected from the cross-matches with 17 external QSO catalogues as detailed below (three of which are parts of ICRF3 described in the first paper). For each Gaia-CRF3 source the information in which external catalogue this source was found and which name(s) this source has in those external catalogues is provided. The table allows the user to get all sources from an external catalogue that are in Gaia-CRF3.The external catalogues from which the Gaia-CRF3 sources were compiled are:

• The third realization of the International Celestial Reference Frame by very long baseline interferometry (Charlot et al. 2020)
