J/ApJS/90/173             PMN map catalog of radiosources       (Gregory+, 1994)

The Parkes-MIT-NRAO (PMN) map catalog of radio sources covering -88° < dec. < -37° at 4.85 GHz Gregory P.C., Vavasour J.D., Scott W.K., Condon J.J. <Astrophys. J. Suppl. Ser. 90, 173 (1994)> =1994ApJS...90..173G
ADC_Keywords: Surveys; Radio sources Keywords: catalogs - radio continuum: general - surveys Abstract: The Parkes-MIT-NRAO (PMN) southern survey was made with the NRAO 4.85GHz seven-beam receiver on the Parkes 64 m telescope during 1990 June, and maps covering the Omega = 2.5 sr declination band -88°<Dec.←37° were constructed from the survey scans. We present a catalog of 15,045 discrete sources with angular sizes phi≲15arcmin and stronger than S∼25mJy 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 4.85GHz weighted source counts S(5/2)n(S) between 30mJy and 10Jy were obtained and agree well with previous results. 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° to -37° 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 <15arcmin and stronger than S∼25mJy 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) and J2000 (file J2000). Each catalog file contains one line per source (15,045 lines each), and the sources are sorted by increasing B1950 or J2000 right ascension. Addresses: Gregory P.C., Vavasour J.D. and Scott W.K.
