J/MNRAS/402/2403 Australia Telescope PMN follow-up survey, ATPMN (McConnell+, 2011) ================================================================================ ATPMN: accurate positions and flux densities at 5 and 8 GHz for 8,385 PMN sources. McConnell D., Sadler E.M., Murphy T., Ekers R.D. ================================================================================ ADC_Keywords: Surveys ; Radio sources ; Keywords: methods: data analysis catalogues surveys radio continuum: general - galaxies: active gamma rays: galaxies Abstract: We present a source catalogue derived from high-resolution observations of a selection of PMN sources with the Australia Telescope Compact Array (ATCA). The catalogue lists 9040 sources with flux-density measurements at 4.8 and 8.6 GHz, derived from observations of all fields in the declination range -87d < delta < -38.5d (exclusive of galactic latitudes |b| < 2d) with PMN flux-density S_{4850} > 70 mJy (50~mJy south of $\delta = -73d). We assess the quality of the data, which was gathered in 1992--1994, and the resulting source parameters. We describe the population of catalogued sources, and compare it to samples from complementary catalogues. In particular we find 126 radio sources with probable association with gamma-ray sources observed by the orbiting Fermi Large Area Telescope. Description: The Australia Telescope PMN catalogue holds the source measurements of flux-density, position and structure of a selection of sources in the PMN catalogue. Each catalogue entry corresponds to a discrete source observed with the ATCA. In many cases a single PMN source yields several ATPMN sources. Apart from the name of the parent PMN source, there is no indication of physical association: multiple sources in the one field may be aligned by chance, or may be components of the one object. The catalogue contains the following information for each source: position; flux-density at 4.8 and 8.6 GHz; uncertainties in each flux-density; source size as the ellipse (major, minor axes, postion angle) of best-fit for a gaussian brightness distribution; spectral index computed between 4.8 and 8.6 GHz; uncertainty in spectral index; a code denoting the epoch of the observation.
