Large catalogues in SIMBAD

We do not systematically process all the catalogues in Simbad, but the CDS also provides the VizieR database which contains published lists of objects, as well as most very large surveys.

Though in the past catalogues like 1RXS or IRAS have been enterely put in Simbad, we do not do that anymore, because the number of objects is exponentially increasing, and because usually only a small percentage of a whole catalogue is actually studied in the literature. Now, we do not want to put all SDSS or 2MASS objects in SIMBAD because SIMBAD focus on the objects of interest.

You can also perform your own cross-match using the dedicated and fast tool : CDS cross-match service.

Gaia DR2

The cross-identification between the SIMBAD database and the ESA Gaia mission Data Release 2 has been successfully performed on June 30, 2018, on about 4.5 million objects.

The following data have been upgraded in SIMBAD :

4.5 million coordinates, Gaia DR2 identifiers, G magnitudes 3.8 million parallaxes 3.8 million proper motions 2.0 million radial velocities
