1994ApJS...90..173G THE PARKES-MIT-NRAO (PMN) MAP CATALOG OF RADIO SOURCES COVERING -88^deg^ < {delta} <-37^deg^ AT 4.85 GHz P. C. GREGORY, J. D. VAVASOUR, AND W. K. SCOTT Physics Department, University of British Columbia, Vancouver, BC, V6T 2A6, Canada AND J. J. CONDON National Radio Astronomy Observatory, 520 Edgemont Road, Charlottesville, VA 22903 Received 1993 April 5; accepted 1993 July 8 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 {phi} <~ 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. Subject headings: catalogs - radio continuum: general - surveys
