Resumen
We present a preliminary analysis of public, deep (200 ksec.) Chandra/ACIS observations of three fields comprising the original Groth-Westphal strip (GWS), gathered from the Chandra Data Archive, combined with optical BVRI data from our broadband survey carried out with the 4.2-m WHT at La Palma. This work has been performed in the framework of the multiwavelength study within the OTELO survey (Cepa et al. 2005)
