Scientific paper

The PMN surveys were made using the Parkes 64-m radio telescope at a frequency of 4850 MHz with the NRAO multibeam receiver mounted at the prime focus (for a full description of the observations see Griffith & Wright, 1993, Paper I). The surveys had a spatial resolution (full width half-maximum: FWHM) of approximately 4'.2 and were made during 1990 June and November. The PMN surveys were divided into several zones. These zones are listed in the following table, together with approximate flux limits and survey areas. -------------------------------------------------------------- Zone Name DEC limits (degrees) Flux limits Area (sr) File -------------------------------------------------------------- SOUTHERN -87.5< dec <-37 20 to 50 mJy 2.50 pmns ZENITH -37 < dec <-29 72 mJy 0.67 pmnz TROPICAL -29 < dec < -9.5 42 mJy 2.01 pmnt EQUATORIAL -9.5< dec <+10.0 40 mJy 1.90 pmne ---------------------------------------------------------------
a point source catalogue 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 (See e.g. our Paper 4). These maps have an effective resolution (FWHM) of about 5 arcmin. For more details, refer to the publications listed below for the relevant zone.
