SPECFIND V3 catalogue

Posted by VizieR Team on 03 December 2021 14:48 CET

The updated SPECFIND V3.0 radio continuum source catalogue, described in this recent Astronomy & Astrophysics paper, has just been released in the VizieR catalogue service. Using 204 radio continuum input catalogue tables from VizieR at CDS in this new version, the authors were able to cross identify 1.6 million radio sources. With these sources, 340 000 radio spectra were created accordingly (as opposed to only 66 000 and 107 000 for the first and second SPECFIND catalogues). Furthermore, the paper identifies a sample of objects that may have a special break in their spectral energy distribution, and require follow-up observation for better identification.
