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 third version of the XMM-Newton OM Serendipitous Ultraviolet Source Survey
Catalogue (XMM-SUSS3) was released in March 2017. In addition to covering a
larger observation period (2000- June 2015), this release differs from the first
one by inclusion of all detected sources in the OM visible filters, in addition
ot 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 now 7,886. The total
number of entries in this updated release is 6,880,116. They correspond to
4,751,899 sources, of which 867,022 have been observed more than once, thus
allowing variability studies.
The XMM-SUSS3 catalogue can be accessed through the XSA search interface.
Further, either the complete catalogue or a reduced version of it can be
downloaded from the XSA.
