CDROM/APJS/V90/P173 PMN Catalog of Radio Sources (Gregory+ 1994) ================================================================================ The Parkes-MIT-NRAO (PMN) Map Catalog of Radio Sources Covering -88 deg < Dec. < -37 deg at 4.85 GHz P. C. Gregory, J. D. Vavasour, W. K. Scott & J. J. Condon <1994, ApJS, 90, 173> =1994ApJS...90..173G ================================================================================ 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 < Dec. < -37 deg were contructed from the survey scans. We present a catalog of 15,045 discrete sources with angular sizes phi <~ 15 arcmin 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. Keywords: catalogs -- radio continuum: general -- surveys Description: 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 (Griffith, M., & Wright, A. E. 1993, AJ, 105, 1666), and maps covering the 2.5 sr declination band -88 deg to -37 deg were constructed from the survey scans (Condon, J. J., Griffith, M., & Wright, A. E. 1993, AJ, 106, 1095). The PMN map catalog of 15,045 discrete sources with angular sizes < 15 arcmin and stronger than S ~ 25 mJy was derived from these maps (Gregory, P. C., Vavasour, J. D., Scott, W. K., & Condon, J. J. 1994, ApJS, 90, 173). A printed version of this catalog with B1950 coordinates is available from the NRAO. There are two machine-readable versions of the PMN map catalog, with coordinates precessed to B1950 (file B1950.DAT) and J2000 (file J2000.DAT). Each catalog file contains one line per source (15,045 lines each), and the sources are sorted by increasing B1950 or J2000 right ascension.
