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 8385 sources with
flux-density measurements at 4.8 and 8.6GHz, derived from observations
of all fields in the declination range -87°<DE←38.5°
(exclusive of galactic latitudes |b|<2{deg{) with PMN flux-density
S4850>70mJy (50mJy south of DE=-73°). 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 8.6GHz; uncertainties in each
flux-density; source size as the ellipse (major, minor axes, position
angle) of best-fit for a gaussian brightness distribution; spectral
index computed between 4.8 and 8.6GHz; uncertainty in spectral index;
a code denoting the epoch of the observation.
