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.

    Abstract:
        The Survey Science Centre of the XMM-Newton satellite released the
        first incremental version of the 2XMM catalogue in August 2008.
        Containing more than 220000 X-ray sources, the 2XMMi was at that time
        the largest catalogue of X-ray sources ever published and thus
        constitutes an unprecedented resource for studying the high-energy
        properties of various classes of X-ray emitters such as AGN and stars.
        Thanks to the high throughput of the EPIC cameras on board XMM-Newton
        accurate positions, fluxes, and hardness ratios are available for a
        substantial fraction of the X-ray detections. The advent of the 7th
        release of the Sloan Digital Sky Survey offers the opportunity to
        cross-match two major surveys and extend the spectral energy
        distribution of many 2XMMi sources towards the optical bands. This
        implies building extensive homogeneous samples with a statistically
        controlled rate of spurious matches and completeness. We here present
        a cross-matching algorithm based on the classical likelihood ratio
        estimator. The method developed has the advantage of providing true
        probabilities of identifications without resorting to heavy
        Monte-Carlo simulations.

    Description:
        Results of the statistical cross-match based on likelihood ratios
        between the incremental Second XMM-Newton Serendipitous Source
        Catalogue (2XMMi) and the Seventh Data Release of the Sloan Digital
        Sky Survey (SDSS DR7). The cross-match is limited to 2XMMi point-like
        sources (epextml<4) with a positional error smaller or equal to 5
        arcsec, and to SDSS DR7 primary sources. We considered the individual
        XMM source detection positions and errors on positions available in
        the XCATDB (http://xcatdb.u-strasbg.fr/2xmmi/home).

        The table contains 72169 distinct associations for 72171 rows. For
        each association, the table provides: parameters extracted from the
        2XMMi catalogue ; cross-match parameters ; and parameters extracted
        from both the SDSS DR7 catalogue and CasJobs
        (http://cas.sdss.org/CasJobs/).

    Note (1): 2XMMi sumflag as follows:
       0 = good
       1 = source parameters may be affected
       2 = possibly spurious
       3 = located in a area where spurious detection may occur
       4 = located in a area where spurious detection may occur
           and possibly spurious
    Note (2): 2XMMi hardness ratios defined as:
       1 = bands 1 & 2
       2 = bands 2 & 3
       3 = bands 3 & 4
       4 = bands 4 & 5
              2XMMi Bands defined as:
       1 = 0.2-0.5keV
       2 = 0.5-1.0keV
       3 = 1.0-2.0keV
       4 = 2.0-4.5keV
       5 = 4.5-12.0keV
       8 = 0.2-12.0keV
       9 = 0.5-4.5keV
    Note (3): Type (class) from SDSS is numbered as follows:
       0 = Unknown: Object type is not known
       3 = Galaxy: An extended object composed of many stars and other matter
       6 = Star: A a self-luminous gaseous celestial body
       8 = Sky: Blank sky spectrogram (no objects in this arcsecond area)
    Note (4): Flag (sc_chflag1) as follows:
       1 = a 2XMM source with unchanged SC parameters
       2 = a 2XMM source with changed SC parameters
       3 = a new source
    Note (5): Flag (sc_chflag2) as follows:
       0 = depends on f1 (sc_chflag1):
           * if f1=1, a unique source present in 2XMM remains unchanged
             in 2XMMi when comprised only of the same detections as in 2XMM.
           * if f1=2, one or more new detections in 2XMMi can, by virtue of
             their spatial separation, simply associate with the group of
             detections from a unique source in 2XMM.
           * if f1=3, new detections in 2XMMi that do not associate with a
             unique source in 2XMM form new unique sources in 2XMMi with
             SRCID values >=191871.
       1 = with f1=2, Detections that formed a source in 2XMM have
           been regrouped, that is, while a source in 2XMMi might map to
           one in 2XMM (having the same source ID and IAU name) it may have
           lost detections it had in 2XMM and it may have gained old
           detections from a different 2XMM source or new detections.
    Note (6): Spectral class as follows:
       0 = Spectrum not classifiable (zConf<0.25)
       1 = Spectrum of a star
       2 = Spectrum of a galaxy
       3 = Spectrum of a quasi-stellar object
       4 = Spectrum of a high-redshift quasar (z>2.3), whose redshift is
           confirmed by a Ly-alpha estimator
       5 = Spectrum of blank sky
       6 = Star dominated by molecular bands M or later
       7 = Emission line galaxy (placeholder)
