Deep BVR photometry of the Chandra Deep Field South from the COMBO-17 survey

Abstract

We report on deep multi-color imaging (R5σ = 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 multi-color survey COMBO-17. As a result we present a catalogue of 63501 objects in a field measuring 31.′5 × 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.
