Deep BVR photometry of the Chandra Deep Field South from the COMBO-17   survey
  We report on deep multi-color imaging (R_5-sigma = 26) of the Chandra Deep Field South, obtained with the Wide Field Imager (WFI) at the MPG/ESO 2.2 m telescope on La Silla as part of the COMBO-17 survey. As a result we present a catalog of 63501 objects in a field measuring 31.5' x 30' with astrometry and BVR photometry. A sample of 37 variable objects is selected from two-epoch photometry. We try to give interpretations based on color and variation amplitude.
