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 first OM catalogue, the XMM-OM Serendipitous Ultra-violet Source Survey (SUSS) was released in August 2008. It is focused on the detections of OM ultraviolet sources, including optical measurements, where available, for all the UV detected objects. The SUSS catalogue contains 750,000 OM sources derived from 2417 XMM OM observations, which cover 29-54 square degrees of sky (dependent on the OM UV filter). Further details are available at XMM-OM Serendipitous Ultra-violet Source Survey (SUSS). The catalogue is accessible through the ESA XSA as well as directly from XMM-OM Serendipitous Ultra-violet Source Survey (SUSS) at MSSL, from OM Catalogue at HEASARC HEASARC, and from CDS. The XMMOM SUSS catalogue provides 3-colour data across the Galex NUV band of sources which, in several cases, have as well X-ray data. Source variability can be obtained from multiple exposures of a single observation or from different observations.
