VizieR Online Data Catalog: 2XMM ultraluminous X-ray source candidates (Walton+, 2011)
Abstract
Through cross-correlation with the RC3 (Cat. VII/155) galaxy catalogue, we have mined the 2XMM Serendipitous Survey (Watson et al., Cat. J/A+A/493/339) to produce a catalogue of ULX candidates. Our catalogue contains 650 detections of 470 discrete sources, and we conservatively estimate that at most ~24 per cent, but more likely ~17 per cent, of these sources are undesirable contaminants, most likely background quasars in this case.
