These surveys were made using the Parkes 64-m radio telescope at a frequency of 4850 Hz with the NRAO multibeam receiver mounted at the prime focus (for a full description of the observations see Griffith & Wright, 1993, Paper I). These surveys had a spatial resolution (full width half-maximum: FWHM) of approximately 4.2 arcminutes and were made during 1990 June and November. The PMN surveys were divided into several zones. These zones are listed below, together with approximate flux limits and survey areas: <pre> Zone Name DEC limits (degrees) Flux limits Area (sr) SOUTHERN -87.5< dec <-37 20 to 50 mJy 2.50 ZENITH -37 < dec <-29 72 mJy 0.67 TROPICAL -29 < dec < -9.5 42 mJy 2.01 EQUATORIAL -9.5< dec <+10.0 40 mJy 1.90 </pre> A point source catalog was compiled directly from each of the survey zones by using an optimum filter method, as described by Griffith & Wright in detail in Paper 1. In addition, a set of images was produced for each zone in a manner very similar to that used by Condon et al. for the northern survey (<a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/40">CDS Catalog VIII/40</a>): See e.g. Paper 4. These maps have an effective resolution (FWHM) of about 5 arcmin. For more details, refer to the publications listed in the References Section for the relevant zone. This updated version of the PMN database was created by the HEASARC in January 2001 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/38">CDS Catalog VIII/38</a>.
