1993AJ....105.1666G THE PARKES-MIT-NRAO (PMN) SURVEYS. I. THE 4850 MHz SURVEYS AND DATA REDUCTION MARK R. GRIFFITH Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 Electronic mail: griffith@maggie.mit.edu ALAN E. WRIGHT Australia Telescope National Facility, Parkes, New South Wales, Australia Electronic mail: awright@atnf.csiro.au Received 1992 October 6; revised 1992 December 21 ABSTRACT We describe radio surveys covering the sky from -87.5^deg^ to +10^deg^ declination made using the Parkes 64 m radio telescope with the NRAO multibeam receiver at a frequency of 4850 MHz during 1990. We have fully reduced the data from the Southern Survey (-87.5^deg^ < {delta} < -37^deg^) and Tropical Survey (-29^deg^<{delta} < -9.5^deg^). Together, these surveys cover 4.51 sr and contain 36640 sources to a flux limit that is, typically, about 35 mJy but varies as a function of declination. They increase the number of known sources in the regions surveyed by approximately a factor of 5. In this paper, we describe the overall PMN Surveys, the data reduction techniques adopted, and assess the data quality of the two lists of sources resulting from the Southern and Tropical Surveys.
