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:
        SUSS4.1 is a new 2018 release of the XMM OM Serendipitous Ultraviolet
        Source Survey catalogue. This new release corrects some
        inconsistencies between IAUNAME and SRCNUM found in the previous
        release (OM SUSS4).

        The catalogue was compiled for the Optical Monitor instrument on board
        the ESA XMM Newton observatory. This version, the 4th release of the
        catalogue, spans the period of observations from 2000 to July 2017.

        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, the fourth
        release differs from the previous one in the implementation of a new
        time dependent sensitivity degradation correction. As in the previous
        release, sources detected on stacked images are properly flagged.

        All data have been fully processed at the European Space Astronomy
        Centre (ESAC, Madrid, Spain) by using the XMM Science Analysis
        Software (SAS) system version 17.0.

        The number of observations (OBSIDs) included in the catalogue is
        9,749. The total number of entries in this release is 8,176,156. They
        correspond to 5,503,765 sources, of which 1,035,453 have multiple
        entries in the source table, corresponding to different observations.

        The Catalogue consists of two tables. The first one (SRCLIST) contains
        the sources, with positional and photometric data (count rate,
        magnitude and flux) and quality flags for each measurement.

        In the second table (SUMMARY) we give a summary of the observations
        from which the sources have been detected and measured.

    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.
