As part of the Great Observatories Origins Deep Survey (GOODS), multi-object spectroscopy of faint galaxies in the Chandra Deep Field South (CDF-S) has been carried out, using the VIMOS instrument mounted at the Melipal Unit Telescope of the VLT at ESO's Cerro Paranal Observatory, Chile.
This data release contains the results of the first half of the GOODS/VIMOS spectroscopic campaign of the ESO/GOODS large programme 171.A-3045 (P.I. C. Cesarsky) which have been obtained in service mode observations using two different grisms (VIMOS 'Low resolution Blue', 3500-6900 Å, and 'Medium resolution Orange', 4000-10000 Å) between fall 2004 and fall 2006. 3312 fully reduced and calibrated spectra of 3121 unique sources down to i₇₇₅=25 AB, along with a catalog of 2000 redshifts of which 985 are classified "high quality" (A) are being released. The 1-sigma redshift accuracy is ~300 km/s and ~200 km/s for the low and the medium resolution observations, respectively. A full description of the survey can be found in the accompanying publication "The Great Observatories Origins Deep Survey: VLT/VIMOS Spectroscopy in the GOODS-South Field" by Popesso et al. 2008, A&A, submitted (astro-ph/0802.2930v1).
