Australia Telescope Hubble Deep Field-South 1.4-GHz Source Catalog
Listed in IVOA Registry (Virtual Observatory)
This table derives from a paper which is part of a series describing the results from the Australia Telescope Hubble Deep Field-South (ATHDFS) survey obtained with the Australia Telescope Compact Array.
Description
This survey consists of observations at 1.4, 2.5, 5.2, and 8.7 GHz, all centered on the Hubble Deep Field-South. Herein are presented the first results from the extended observing campaign at 1.4 GHz.
A total of 466 sources have been cataloged to a local sensitivity of 5-sigma (11 µJy rms). A source extraction technique is developed that (1) successfully excludes spurious sources from the final source catalogs and (2) accounts for the nonuniform noise in the image. A source catalog is presented, and the general properties of the 1.4-GHz image are discussed in the reference paper.

In the latter, the authors also present source counts derived from their ATHDFS 1.4-GHz catalog. The 1.4 GHz observations were carried out by the Australia Telescope Compact Array over 4 years from 1998 to 2001. They consist of single pointings centered on RA (J2000.0) = 22<sup>h</sup> 33<sup>m</sup> 25.96<sup>s</sup>, Dec (J2000.0) = -60<sup>o</sup> 38' 09.0".
