Gaia-CRF3 cross match table

As described in Gaia Collaboration et al. 2021 the Gaia-CRF3 was constructed from a filtered cross-match of Gaia EDR3 astrometric catalogue and 17 external catalogues of QSOs and AGNs. The table that can be downloaded below contains full information in which catalogues the Gaia-CRF3 sources were found. The use of this table is described in Appendix B of the paper. This Table will appear in the Gaia Archive as "gaiadr3.gaia_crf3_xm" as a part of the full Gaia Data Release 3.
