The field reaches the following limiting magnitudes: BAB∼25.3, VAB∼24.8 and RAB∼25.1 and contains ∼50000 extended sources in the magnitude range 18≤RAB≤25.0. Hence, it is intermediate between deep pencil beam surveys and very wide but shallow surveys. Description: Magnitudes and spectroscopic information for 173 sources in the Capodimonte Deep Field are provided. The magnitudes were derived from images obtained with the ESO Wide-Field Imager at the ESO 2.2m telescope at la Silla, Chile. Spectroscopic information for the whole sample of 173 sources was extracted from spectra obtained with the ESO-NTT using EMMI-MOS at La Silla, Chile. The catalog contains AB magnitudes in the B, V, R and I broad bands and in the 753, 770, 791, 816, 837, 884 and 913 intermediate band filters, as well as spectroscopic redshifts and stellar spectral types.
