The OM team, under the auspices of the SSC, produces a catalogue of sources detected by the Optical Monitor. This catalogue, like the EPIC catalogue, is based on the pipeline processed products.
The second version of the XMM-Newton OM Serendipitous Ultraviolet Source Survey Catalogue (XMM-SUSS2) was released in March 2014. In addition to covering a larger observation period (2000-2012), this release differs from the previous one by inclusion of all detected sources in the OM visible filters, besides the UV filters, and by performing source detection on stacked images facilitating the detection of fainter sources.
The number of observations included in the catalogue is 6,604. The total number of entries in this second release is 5,595,331. They correspond to 4,008,879 sources, of which 692,223 have been observed more than once, thus allowing variability studies.
The XMM-SUSS2 catalogue can be accessed through the XSA search interface. Besides, either the complete catalogue or a reduced version of it can be downloaded from the XSA.
