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
-88deg<Dec.<-37deg 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 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 <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.
