The Parkes-MIT-NRAO (PMN) Map Catalog of Radio Sources Covering -88 degrees < delta < -37 degrees at 4.85 GHz
Abstract
The Parkes-MIT-NRAO (PMN )southern survey was made with the NRAO 4.85 GHz seven-beam receiver on the Parkes 64 m telescope during 1990 June, and maps covering the {OMEGA} = 2.5 sr declination band -88^deg^< b < - 37^deg^ were constructed from the survey scans. We present a catalog of 15,045 discrete sources with angular sizes φ <~ 15' and stronger than S~25 mJy derived from these maps. Machine-readable versions of the catalog with either B1950 or J2000 positions, and a printed catalog with B1950 positions only, are available. The 4.85 GHz weighted source counts S^5/2^n(S) between 30 mJy and 10 Jy were obtained and agree well with previous results.
