Scientific paper

The Parkes-MIT-NRAO (PMN) southern survey was made with the National Radio Astronomy Observatory (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 less than delta less than -37 deg were constructed from the survey scans. We present a catalog of 15,045 discrete sources with angular sizes phi approximately less than 15 min and stronger than S approximately 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 S5/2n(S) between 30 mJy and 10 Jy were obtained and agree well with previous results.
