Abstract:
We present a catalog of photometry and photometric redshifts of 335
faint objects in the Hubble Deep Field South (HDF-S) near-infrared
camera and multiobject spectrograph (NICMOS) field. The analysis is
based on (1) infrared images obtained with the Hubble Space Telescope
(HST) using the NICMOS with the F110W, F160W, and F222M filters; (2)
an optical image obtained with HST using the Space Telescope Imaging
Spectrograph with no filter; and (3) optical images obtained with the
European Southern Observatory Very Large Telescope with U, B, V, R,
and I filters. The primary utility of the catalog of photometric
redshifts is as a survey of faint galaxies detected in the NICMOS
F160W and F222M images. The sensitivity of the survey varies
significantly with position, reaching a limiting depth of
AB(1.6µm)∼28.7 and covering 1.01arcmin2 to AB(1.6µm)=27
and 1.05arcmin2 to AB(1.6µm)=26.5. The catalog of photometric
redshifts identifies 21 galaxies (or 6% of the total) of redshift z>5,
eight galaxies (or 2% of the total) of redshift z>10, and 11 galaxies
(or 3% of the total) of best-fit spectral type E/S0, of which five
galaxies (or 1% of the total) are of redshift z>1.

Note on wfphot.dat: The data of two sources, SB-WF-1413-2011 and
SB-WF-2592-4053 where suppressed of this table, because of the
non-reliability of the data. The original data are reported in the
errorwf.dat file, in the same format as wfphot.dat file.
