The FORS Deep Field: Photometric Data and Photometric Redshifts.

Deep multicolor fields are an important tool to explore the formation and evolution of galaxies out to the highest redshifts and faintest magnitude limits (Ferguson et al. [11]). This is also the aim of the FORS Deep Field (FDF), which has about 5 times the field-size of the two Hubble Deep Fields together and, in addition, contains a relatively bright quasar of 18.5mag at z = 3.36 at its center. A full exploration of the FDF multicolor data requires good photometric redshifts. In this paper we provide an overview of the data, describe our photometric redshift technique and present the redshift distribution in the FDF. [ABSTRACT FROM AUTHOR]
