The FORS Deep Field project is a multi-colour, multi-object
spectroscopic investigation of a ∼
region near the south galactic pole based mostly on
observations carried out with the FORS instruments attached
to the VLT telescopes. It includes the QSO Q 0103-260 (
).
The goal of this study is to improve our understanding of
the formation and evolution of galaxies in the young Universe.
In this paper the field selection, the photometric observations, and the data
reduction are described. The source detection and photometry of objects in the
FORS Deep Field is discussed in detail. A combined B and I selected UBgRIJKs
photometric catalog of 8753 objects in the FDF is presented and its
properties are briefly discussed. The formal 50% completeness limits
for point sources, derived from the co-added images,
are 25.64, 27.69, 26.86, 26.68, 26.37, 23.60 and 21.57
in U, B, g, R, I, J and Ks (Vega-system), respectively. A comparison of
the number counts in the FORS Deep Field to those derived in
other deep field surveys shows very good agreement.
