Abstract:
We present the Capodimonte Deep Field (OACDF), a deep field covering
an area of 0.5°2 in the B, V, R optical bands plus six
medium-band filters in the wavelength range 773-913nm. 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.
