Abstract:
The Phoenix Deep Survey is a multiwavelength galaxy survey based on
deep 1.4GHz radio imaging. The primary goal of this survey is to
investigate the properties of star formation in galaxies and to trace
the evolution in those properties to a redshift z=1, covering a
significant fraction of the age of the universe. By compiling a sample
of star-forming galaxies based on selection at radio wavelengths we
eliminate possible biases due to dust obscuration, a significant issue
when selecting objects at optical and ultraviolet wavelengths. In this
paper, we present the catalogs and results of deep optical (UBVRI) and
near-infrared (Ks) imaging of the deepest region of the existing
decimetric radio imaging. The observations and data processing are
summarized and the construction of the optical source catalogs
described, together with the details of the identification of
candidate optical counterparts to the radio catalogs. Based on our
UBVRIKs imaging, photometric redshift estimates for the optical
counterparts to the radio detections are explored.
Description:
Two pointings (7, 3) were observed in BVRi, and one (pointing 11) in
BVi on the nights of 2001 August 13 and 14, with the WFI camera on the
AAT. The same three pointings were also observed in U with the
Mosaic-II camera on the CTIO 4m Blanco telescope on 2002 September 3.
Finally, four of the PDS fields (2, 3, 6, 7) were observed in U with
the WFI on the ESO 2.2m on the night of 2001 August 18. Our NIR
imaging data come from the Hawaii HgCdTe 1024x1024 pixel array SoFI
camera on the 3.6m ESO New Technology Telescope (NTT). The field of
view was 4.9'x4.9' with a pixel scale of 0.29". Nine contiguous
pointings, in a 3x3 pattern, were observed over the deepest region of
the PDS (a subregion of pointing 7; see Fig. 1), during 2000 October
10 and October 11.

Note (1): when the magnitude measured is below the 5σ detection
threshold, it is flagged with a '1'; when the net flux is negative,
the formal 5σ limit is given and the '>' limit is written.
