Query: The Great Observatories Origins Deep Survey. VLT/FORS2 Spectroscopy in
  the GOODS-South Field: Part III   Aims. We present the full data set of the spectroscopic campaign of the
  ESO/GOODS program in the GOODS-South field, obtained with the
  FORS2 spectrograph at the ESO/VLT. Method. Objects were selected as
candidates for VLT/FORS2 observations primarily based on the expectation that
the detection and measurement of their spectral features would benefit from the
high throughput and spectral resolution of FORS2. The reliability of the
redshift estimates is assessed using the redshift-magnitude and color-redshift
diagrams, and comparing the results with public data. Results. Including the
third part of the spectroscopic campaign (12 masks) to the previous work (26
masks, Vanzella et al. 2005, 2006), 1715 spectra of 1225 individual targets
have been analyzed. The actual spectroscopic catalog provides 887 redshift
determinations. The typical redshift uncertainty is estimated to be sigma(z) ~
0.001. Galaxies have been selected adopting different color criteria and using
photometric redshifts. The resulting redshift distribution typically spans two
domains: from z=0.5 to 2 and z=3.5 to 6.3. The reduced spectra and the derived
redshifts are released to the community through the ESO web page
