Abstract:
This paper 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. This survey consists of
observations at 1.4, 2.5, 5.2, and 8.7GHz, all centered on the Hubble
Deep Field-South. Here we present the first results from the extended
observing campaign at 1.4GHz. A total of 466 sources have been
cataloged to a local sensitivity of 5σ (11µJy 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 our image. A source catalog is presented, and
the general properties of the 1.4GHz image are discussed. We also
present source counts derived from our ATHDFS 1.4GHz catalog.

Note (1): The values given here are not corrected for the systematic effects
described in Section 3. Appendix A describes how to obtain source
peak flux densities corrected for the systematic effects.
Note (2): Zero values refer to unresolved sources (see Section 4.3).
Note (3): Measured from N through E of the source. Zero values refer to
unresolved sources (see Section 4.3).
Note (4): Calculated as IMSAD fitted peak/σlocal.
Note (5): Gaussian fit quality flag, defined as follows:
1 = very good fit;
2 = poor integrated flux density;
n = non-Gaussian sources. See Section 4.2 for more details.
Note (6): Components of a multiple source are indicated with the ID of the
other source(s) with which they are associated. See Section 4.4
for more details.
