我们报告我们的钱德拉深场南（CDFS）的H波段调查的结果。使用SofI在NTT上进行的观测覆盖了0.027平方度（H < 20.5）和0.17平方度（H < 19.8）（50%完整性限制）。总共探测到4819个天体，其中80%是基于SExtractor参数“恒星度指数”的星系，其值小于0.5。我们的天体测量解与拉斯坎帕纳斯红外巡天（LCIRS）、COMBO-17和ESO-EIS巡天的解非常一致。我们的光度比较令人满意的LCIRS的结果，以及与GOODS数据。在H< 20.75时，每平方度的星系数为50000个，与LCIRS的结果一致。天体目录以电子方式在CDS？？.
We report results of our H-band survey of the Chandra Deep Field South (CDFS). The observations, made with SofI on the NTT, cover 0.027 square degrees to H < 20.5 and 0.17 square degrees to H < 19.8 (50% completeness limits). In total, 4819 objects were detected, of which 80% are galaxies based on the SExtractor parameter "stellarity index" having a value less than 0.5. Our astrometric solutions are in good agreement with those of the Las Campanas Infrared Survey (LCIRS), the COMBO-17, and the ESO-EIS surveys. Our photometry compares satisfactorily with the LCIRS results as well as with GOODS data. Galaxy number counts are50 000 galaxies per square degree at H< 20.75, in good agreement with those of LCIRS. The object catalog is published electronically at the CDS ?? .
