Description
SUSS5.0 is a new 2020 release of the XMM OM Serendipitous Ultraviolet Source Survey catalogue. his release is largely an increment of the previous XMM-OM-SUSS4.1 release but includes flagging of sources affected by a patch of reduced sensitivity near the centre of the OM field of view. The catalogue was compiled for the Optical Monitor instrument on board the ESA XMM Newton observatory. This version, the 5th release of the catalogue, spans the period of observations from XMM-Newton revolution 34 (February 2000) to revolution 3704 (February 2020). A detailed description of the Catalogue can be found at https://www.ucl.ac.uk/mssl/research-projects/2018/dec/xmm-newton. A refereed paper on the first version can be found in Page M.J. et al. (2012MNRAS.426..903P). In addition to covering a larger observation period, this fifth release includes flagging of sources affected by a patch of reduced sensitivity near the boresight, caused by erroneously V-filter exposures during an observation of Jupiter in July 2017 (revolution 3224). All data have been fully processed at the European Space Astronomy Centre (ESAC, Madrid, Spain) using the XMM Science Analysis Software (SAS) system version 18.0. The number of observations (OBSIDs) included in the catalogue is 10,628. The total number of entries in this release is 8,863,922. They correspond to 5,965,434 sources, of which 1,120,754 have multiple entries in the source table, corresponding to different observations. The Catalogue is a FITS file consisting of two tables (please note that users wishing to use the TOPCAT tool to manipulate the catalogue, need to select the table format option, "FITS" to load the catalogue). The first one (SRCLIST) contains the sources, with positional and photometric data (count rate, magnitude and flux) and quality flags for each measurement.
