ADC_Keywords: Surveys ; Radio sources ; Redshifts ; Photometry, UBVRI ; Spectroscopy Keywords: radio continuum: galaxies - surveys Abstract: The Australia Telescope Hubble Deep Field-South (ATHDF-S) survey of the Hubble Deep Field-South (HDF-S) reaches sensitivities of ∼10uJy at 1.4, 2.5, 5.2, and 8.7GHz, making the ATHDF-S one of the deepest surveys ever performed with the Australia Telescope Compact Array (ATCA). Here, we present the optical identifications of the ATHDF-S radio sources using data from the literature. We find that ∼66% of the radio sources have optical counterparts to I=23.5mag. Deep Hubble Space Telescope (HST) imaging of the area identifies a further 12% of radio sources. We present new spectroscopic observations for 98 of the radio sources and supplement these spectroscopic redshifts with photometric ones calculated from five-band optical imaging. Description: The radio observations and data reduction are detailed in Papers I-III (Norris et al., 2005, Cat. J/AJ/130/1358; Huynh et al., 2005, Cat. J/AJ/130/1373; Huynh et al., 2007, Cat. J/AJ/133/1331) Palunas et al. (2000ApJ...541...61P) observed the HDF-S region using the Big Throughput Camera (BTC) on the Cerro Tololo Inter-American Observatory (CTIO) 4m during 1998 September. Images were taken in the Sloan Digital Sky Survey (SDSS) u, Johnson B and V, and Cousins R and I filters. File Summary:

Note (1): A value of 3 indicates three or more lines were identified, so the redshift is very well determined. Two, one or no lines identified are indicated by Q = 2, 1 or 0, respectively. Note (2): Spectral type code as follows: abs = galaxy with absorption lines sf = star-forming galaxy sy = Seyfert BL = broad-line AGN unc = unclassified
