THE PARKES-MIT-NRAO (PMN) SURVEYS .3. SOURCE CATALOG FOR THE TROPICAL SURVEY (-29-DEGREES-LESS-THAN-DELTA-LESS-THAN-9-DEGREES.5)

We present a catalog of radio sources discovered at a frequency of 4850 MHz in the tropical zone (-29-degrees < delta < -9.5-degrees) 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 a previous paper (Griffith & Wright 1993). In this paper, we describe the specific details of the tropical survey, and we list the sources for the tropical survey. Later papers in the series will list objects for other survey zones, describe images made from the data, and provide analysis of the data.
