One of the aims of this survey is to characterize the submillijansky radio population, exploring its nature and evolution. In this paper we present the catalog and results of the spectroscopic observations aimed at characterizing the optically "bright" (R≲21.5mag) counterparts of faint radio sources. Of 371 sources with redshift determination, 21% have absorption lines only, 11% show active galactic nucleus signatures, 32% are star-forming galaxies, 34% show narrow emission lines that do not allow detailed spectral classification (owing to poor signal-to-noise ratio and/or lack of diagnostic emission lines), and the remaining 2% are identified with stars. Description: The PDS includes a deep 1.4GHz survey made using the Australia Telescope Compact Array covering an area of 4.56deg2 (the Phoenix Deep Field, PDF), selected to lie in a region of low optical obscuration and devoid of bright radio sources. Optical CCD imaging was carried out at the Anglo-Australian Telescope (AAT) in the R and V bands, as detailed in Georgakakis et al. (1999, Cat. J/MNRAS/306/708). Optical counterparts of radio sources in the PDS were observed spectroscopically in a series of observing campaigns. Initial data were obtained using multifiber spectroscopy at the Two Degree Field (2dF) spectrograph at the AAT (1996 December and 1997 September) and slit spectroscopy at the ESO 3.6m telescope (1996 October).

Note (1): Vega-based system Note (2): Following Sutherland (1992MNRAS.259..413S). Note (3): In units of Angstroms. Note (4): Uncorrected for any stellar absorption. Note (5): Spectrum quality parameter as follows: A = a high quality spectrum, with a firmly established redshift B = a low S/N spectrum, where a redshift was established using at least 2 spectral features C = only one spectral feature is identified Note (6): Spectral classification as follows: uncl = classification was not possible sf = star-forming abs = absorption line system Sey2 = Seyfert 2 star = star Sey1 = Seyfert 1
