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. File Summary:

See text for more details. Note (3): The comments are not meant to be an exhaustive list of features seen in each spectrum, and simply includes clearly-detected features used for redshift measurement. He5876 refers to He I emission; N6548 and N6583 refer to [N II] emission; O3727 refers to [O II] emission; O4959 and O5007 refer to [O III] emission; Ne3869 refers to [Ne III] emission; H and K refer to Ca II absorption; G refers to G-band absorption; For the purposes of this table, Hα, Hβ, Hγ, and Hδ refer to emission lines Hη and Hζ refer to absorption lines.
