Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Description:
        SUSS5.0 is a new 2020 release of the XMM OM Serendipitous Ultraviolet
        Source Survey catalogue. This 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.

    Note (1): Sources are designated as "XMMOM JHHMMSS.s+DDMMSSa", conform to
         the IAU Working Group on Designations (old IAU Commission 5). There are
         over 1173 non-unique names. The last character is optional, and only
         used to distinguish sources which otherwise would have the same name.
    Note (2): the quality flags are as a set of the corresponding T/F (True/False)
          characters.
          1 : T = source on a bad pixel
          2 : T = source on a readout streak
          3 : T = source on a smoke-ring
          4 : T = source on a diffraction spike
          5 : T = source affected by Mod-8 pattern
          6 : T = source within the central enhancement
          7 : T = source lies near a bright source
          8 : T = source near the edge
          9 : T = point source within an extended source
         10 : T = very bight pixel within photometry aperture
         11 : T = multiple exposure values within photometry aperture
         12 : T = the source is too bright (rate>0.97ct/frame)
    Note (3): the flag is 1 for an extended source and 0 for a point source.
