This catalog can be used for statistical analyses, accompanied with the corrections given in the data & catalog release paper (Smolcic et al. 2016). All completeness & bias corrections and source counts presented in Smolcic et al. (2016) were calculated using this sample. The total fraction of spurious sources in the COSMOS 2 sq.deg. is below 2.7% within this catalog. However, an increase of spurious sources (up to 24% at 5.0<S/N<5.5) is present (for details see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). A subsample with a minimal spurious source fraction can be selected by requiring a signal-to-noise ratio SNR # 5.5 (see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). The total fraction of spurious sources in the COSMOS 2 sq.deg. within such a selected sample is below 0.4%, and the fraction of spurious sources is below 3% even at the lowest SNR (=5.5).", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/data/COSMOS/gator_docs/cosmos_vla3ghz_colDescriptions.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/SCS?table=cosmos_vla3ghz&", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "ivo://irsa.ipac/cosmos/catalog/cosmosvla3ghz", "keyword": ["__"], "landingPage": "ivo://irsa.ipac/cosmos/catalog/cosmosvla3ghz", "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/IPAC Infrared Science Archive"}, "theme": ["Astrophysics"], "title": "COSMOS VLA 3GHz Catalog"}
