Description:
  The first source catalog contains radio sources discovered at a
  frequency of 4850 MHz in the Southern zone (-87.5 < DEC < -37 ) of
  the Parkes-MIT-NRAO (PMN) survey. This survey covers 2.50 sr and
  23,277 sources to a flux limit which varies as a function of
  declination from 20 mJy at the southern survey limit to about 50 mJy
  at the northern limit. The new survey increases the number of radio
  sources known in the area surveyed by a factor of ~5 over those
  found by either of the earlier Parkes or Molonglo surveys. 
  The second source catalog is a catalog of radio sources discovered
  at a frequency of 4850 MHz in the Tropical zone (-29 < dec < -9.5
  deg ) of Parkes-MIT-NRAO (PMN) Surveys. The Tropical Survey covers
  2.01 sr and contains 13,363 sources to a flux limit that is,
  typically, about 42 mJy but varies as a function of declination. The
  survey was made using the Parkes 64 m radio telescope with the NRAO
  multibeam receiver during 1990. This survey increases the number of
  known sources in the region surveyed by approximately a factor of 5.
  The data taking and principal reduction methods used for the PMN
  Surveys have been extensively described in the paper of Griffith &
  Wright (1993). The second catalog contains the specific details of
  the Tropical Survey and lists the sources for the Survey.
