| This table contains brief descriptions of the parameters provided for each source in the catalogue of the Chandra Deep Field South with multi-colour classification and photometric redshifts from COMBO-17. The table contains positions, flags and flux measurements in UBVRI and 12 optical medium-band filters. In addition, multi-colour classification, photometric redshifts, luminosity distances and a number of absolute restframe magnitudes in different filters (Johnson, Sloan, Bessell) are included as well.
