| # Detailed Description of J/ApJS/90/173 : PMN map catalog of radiosources (Gregory+, 1994) |

Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    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.
