                                 ABSTRACT
   The initial Phoenix Deep Survey (PDS) observations with the Australia
Telescope Compact Array have been supplemented by additional 1.4 GHz
observations over the past few years. Here we present details of the
construction of a new mosaic image covering an area of 4.56 deg^2^, an
investigation of the reliability of the source measurements, and the 
1.4 GHz source counts for the compiled radio catalog. The mosaic achieves 
a 1 {sigma} rms noise of 12 microJy at its most sensitive, and a 
homogeneous radio-selected catalog of over 2000 sources reaching flux 
densities as faint as 60 microJy has been compiled. The source parameter 
measurements are found to be consistent with the expected uncertainties 
from the image noise levels and the Gaussian source fitting procedure. 
A radio-selected sample avoids the complications of obscuration associated 
with optically selected samples, and by utilizing complementary PDS 
observations, including multicolor optical, near-infrared, and 
spectroscopic data, this radio catalog will be used in a detailed 
investigation of the evolution in star formation spanning the redshift 
range 0 < z < 1. The homogeneity of the catalog ensures a consistent 
picture of galaxy evolution can be developed over the full cosmologically 
significant redshift range of interest. The 1.4 GHz mosaic image and the 
source catalog are available on the World Wide Web; or from the authors by 
request.
