ADC_Keywords: Galaxies, spectra ; Redshifts ; Photometry, infrared Keywords: cosmology: observations - cosmology: large scale structure of the universe - Galaxy: general Abstract: We present the second results of the ESO/GOODS program of spectroscopy of faint galaxies in the Chandra Deep Field South (CDF-S). The typical redshift uncertainty is estimated to be sigmaz∼0.001. The reduced spectra and the derived redshifts are released to the community through the ESO web page Description: The VLT/FORS2 spectroscopic observations were carried out in service mode during several nights at the end of 2003 and the beginning of 2004.

Note (1): Groups the objects for which emission line(s) (em.), absorption-line(s) (abs.) or both (comp.) are detected in the spectrum. The classification has been guided by the observed continuum level and slope blueward and redward of the emission/absorption feature, by the broad-band colors and the morphology of the targets. Note (2): Quality flag for the reliability of the redshift determination, as follows: A = solid redshift determination (150 objects) B = likely redshift determination (57 objects) C = tentative redshift determination (27 objects) X = an inconclusive spectrum Note (3): The column contains additional information relevant to the particular observation. The most common ones summarize the identification of the principal lines, the inclination of an emission line due to internal kinematics, the weakness of the signal ("faint"), the low S/N of the extracted spectrum ("noisy"), the 20% light radius ("Flux-radius" in ACS pixels) for objects classified as stars, etc.
