We find 268 sources detected both in the X-ray and radio bands. The availability of redshifts for ∼95 per cent of the sources in our sample allows us to derive reliable luminosity estimates and the intrinsic properties from X-ray analysis for the majority of the objects. Description: In the E-CDF-S area, we have two sets of X-ray data obtained with Chandra. The most important is a 4-Ms exposure observation resulting from the co-addition of 54 individual Chandra ACIS-I exposures from 1999 October to 2010 July, with centres spaced within a few arcseconds from RA=03:32:28.80, DE=-27:48:23 (J2000). We consider the data from the new VLA programme which provides deep, high-resolution 1.4-GHz imaging across the full E-CDF-S, consisting of a six-pointing mosaic of 240 h spanning 48 d of individual 5-h observations (Miller et al., 2008, Cat. J/ApJS/179/114). The E-CDF-S area has been targeted by a large number of spectroscopic surveys. For the X-ray sources, we use the spectroscopic redshift published in Xue et al. (2011, Cat. J/ApJS/195/10). File Summary:
