The ECDF-S area has been a frequent target of X-ray observations with both Chandra and XMM. After the first 1Ms Chandra observation (Giacconi et al., 2002, Cat. J/ApJS/139/369), the area was named the Chandra Deep Field South. The extension of the CDF-S survey to 2Ms (Luo et al., 2008, Cat. J/ApJS/179/19) and later to 4Ms of exposure time (Xue et al., 2011, Cat. J/ApJS/195/10), via a large Director's Discretionary Time project, has now provided our most sensitive 0.5-8keV view of the distant AGNs and galaxies. This paper does not include the 3Ms Chandra observations of the field taken in 2014. For cataloguing the groups, we also include the ECDF-S data (Lehmer et al., 2005, Cat. J/ApJS/161/21), which consist of four Chandra ACIS-I pointings, 250ks each, defining the square shape of the exposure and sensitivity maps. (1 data file).
