Abstract:
We present a catalog of 97 (*) spectroscopic redshifts of z<1 galaxies
in the Hubble Deep Field South (HDF-S) and its flanking fields (FFs).
In the HDF-S proper we observed approximately half the galaxies
brighter than I814(AB)=24 and obtained redshifts for 76% of them.
Targets in our HDF-S sample were preselected to be at z<1 based on
photometric redshifts, while in the FFs a simple magnitude cut was
used. The photometric redshift preselection in the HDF-S resulted in a
spectroscopic success rate that is significantly higher than in the
FFs, where no preselection was applied. The rms precision of our
redshift measurements, determined from repeat observations, is
δz=0.0003. We present the photometry and redshifts for the 97
objects for which we secured spectroscopic redshifts and describe the
basic properties of this sample.
The photometry was derived from the HST observations; the spectroscopy
was obtained at the VLT using the FORS2 spectrograph on the Kueyen
(UT2) and Yepun (UT4) 8.2m telescopes.
(*) Actually, 103 redshifts in table1.
