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 http://www.eso.org/science/goods/
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.
