THE PARKES-MIT-NRAO (PMN) SURVEYS. I.
THE 4850 MHz SURVEYS AND DATA REDUCTION

Griffith, M. R. & Wright, A. E. 1993, AJ, 105, 1666

Abstract

We describe radio surveys covering the sky from -87°.5 to +10° declination made using the Parkes 64 m radio telescope with the NRAO multi-beam receiver at a frequency of 4850 MHz during 1990. We have fully reduced the data from the Southern Survey (-87°.5 < δ < -37°) and Tropical Survey (-29° < δ < -9.5°). Together, these surveys cover 4.51 sr and contain 36,640 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.

SOURCE CATALOG FOR THE SOUTHERN SURVEY (-87°.5 < δ < -37°)

Abstract

We present a catalog of radio sources discovered at a frequency of 4850 MHz in the Southern zone (-87°.5 < δ < -37°) of the Parkes-MIT-NRAO (PMN) survey. This survey covers 2.50 sr and contains 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 ~ P5 over those found by either of the earlier Parkes or Molonglo surveys. We described our data taking and reduction methods for the PMN survey in a previous paper. In this paper we tabulate the sources for the Southern Survey. Instructions are also given for obtaining the data in machine-readable form. Later papers in the series will list objects for other survey zones and provide analysis of the data.


THE PARKES-MIT-NRAO (PMN) SURVEYS. III.
SOURCE CATALOG FOR THE TROPICAL SURVEY (-29° < δ < -9°.5)

Griffith, M. R., Wright, A. E., Burke, B. F., & Ekers, R. D. 1994, ApJS, 90, 179

Abstract

We present a catalog of radio sources discovered at a frequency of 4850 MHz in the Tropical zone (-29° < δ < -9°.5) 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; hereafter "Paper 1"). 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.


THE PARKES-MIT-NRAO SURVEYS. IV.
MAPS FOR THE SOUTHERN SURVEY COVERING -88° < δ < -37°

Condon, J. J., Griffith, M. R., & Wright, A. E. 1993, AJ, 106, 1095

Abstract

The NRAO seven-beam receiver was used on the Parkes 64 m telescope during 1990 June to make the Parkes-MIT-NRAO (PMN) 4.85 GHz continuum sky surveys of the declination band -88° < δ < -9°. The PMN Southern Survey covering -88° < dec < -37° was reduced with AIPS to yield total-intensity maps covering ~ 2.5 sr with ~ 5' FWHM resolution (~4x10^5 beams/sr). The rms map noise plus confusion increases from ~ 5 mJy/beam near the south celestial pole to ~ 10 mJy at δ = -40°. The rm position uncertainties on the maps vary from 6" in each coordinate for the strongest sources to 30" at S = 5 sigma. Sets of maps precessed to B1950 and J2000 coordinates are available on a FITS tape for quantitative analysis.


THE PARKES-MIT-NRAO SURVEYS. V.
MAPS FOR THE TROPICAL SURVEY COVERING -29° < δ < -9°

Tasker, N. J., Condon, J. J., Wright, A. E., & Griffith, M. R. 1994, AJ, 107, 2115

Abstract

The Parkes-MIT-NRAO (PMN) 4.85 GHz continuum survey of the southern sky was undertaken in 1990 June and November and covered -88° < δ < -9°. This survey used the Parkes 64 m Telescope of the Australia Telescope National Facility and the NRAO seven-be am receiver. This paper describes the maps for the Tropical Survey zone covering the declination band -29° < δ < -9°, which were produced using the Astronomical Image Processing System (AIPS). The maps have a FWHM resolution of ~ 5'. The rms uncertainty in position for strong sources is 10" in right ascension and 8" in declination. This uncertainty increases to ~ 30" in both right ascension and declination for sources near the flux limits. The rms map brightness fluctuations caused by noise and confusion increase from 9 mJy/beam at δ~ -9° to 11 mJy/beam at δ ~ -29°.


THE PARKES-MIT-NRAO (PMN) SURVEYS. VI.
SOURCE CATALOG FOR THE EQUATORIAL SURVEY (-9°.5 < δ < +10°.0)

Griffith, M. R., Wright, A. E., Burke, B. F., & Ekers, R. D. 1995, ApJS, 97, 347

Abstract

We present a catalog of radio sources discovered at a frequency of 4850 MHz in the equatorial zone (-9°.5 < δ < +10°) of the Parkes-MIT-NRAO (PMN) Surveys. The equatorial survey covers 1.90 sr and contains 11,774 sources to a flux limit of 40 mJy. The survey was made using the Parkes 64m radio telescope with the NRAO multibeam receiver during 1990. This survey largely overlaps the 87GB survey in the declination range +1° to +10°. The data-taking and principal reduction methods used for the PMN Surveys have been extensively described in previous papers. In this paper, we describe the specific details of the equatorial survey and we provide a list of sources. Later papers in the series will describe images made from, and provide analysis of, the data.

Wright, A. E., Griffith, M. R., Hunt, A. J., Troup, E., Burke, B. F., & Ekers, R. D. 1996, ApJS, 103, 145

Abstract

We present a catalog of radio sources discovered at a frequency of 4850 MHz in the zenith zone (-37° < δ < -29°) of the Parkes-MIT-NRAO (PMN) surveys. The zenith survey covers 0.677 sr and contains 2400 sources to a flux limit of 72 mJy. The survey was made using the Parkes 64 m radio telescope with the NRAO multibeam receiver during 1990. The data-taking and principal reduction methods used for the PMN surveys have been extensively described in previous papers. In this paper, we describe the specific details of the zenith survey and we provide a list of sources. Later papers in the series will describe the images made from, and provide analysis of, the data.
