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:
        We have created a new, clean catalogue of extragalactic non-nuclear
        X-ray sources by correlating the 3XMM-DR4 data release of the
        XMM-Newton Serendipitous Source Catalogue with the Third Reference
        Catalogue of Bright Galaxies and the Catalogue of Neighbouring
        Galaxies, using an improved version of the method presented in Walton
        et al. (2011MNRAS.416.1844W, Cat. J/MNRAS/416/1844). Our catalogue
        contains 1314 sources, of which 384 are candidate ultraluminous X-ray
        sources (ULXs). The resulting catalogue improves upon previous
        catalogues in its handling of spurious detections by taking into
        account XMM-Newton quality flags. We estimate the contamination of
        ULXs by background sources to be 24 per cent. We define a 'complete'
        subsample as those ULXs in galaxies for which the sensitivity limit is
        below 1039erg/s and use it to examine the hardness ratio properties
        between ULX and non-ULX sources, and ULXs in different classes of host
        galaxy. We find that ULXs have a similar hardness ratio distribution
        to lower-luminosity sources, consistent with previous studies. We also
        find that ULXs in spiral and elliptical host galaxies have similar
        distributions to each other independent of host galaxy morphology,
        however our results do support previous indications that the
        population of ULXs is more luminous in star-forming host galaxies than
        in non-star-forming galaxies. Our catalogue contains further
        interesting subpopulations for future study, including Eddington
        Threshold sources and highly variable ULXs. We also examine the
        highest-luminosity (LX >5x1040erg/s) ULXs in our catalogue in
        search of intermediate-mass black hole candidates, and find nine new
        possible candidates

    Description:
        Through cross-correlation with the RC3 (de Vaucouleurs et al., 1991,
        Cat. VII/155) and LV (Karachentsev et al., 2004, Cat.
        J/AJ/127/2031/LV) galaxy catalogues, we have used the 3XMM-DR4
        Serendipitous Source Catalogue (XMM-SSC, 2013, Cat. IX/44) to produce
        a catalogue of non-nuclear X-ray sources in nearby galaxies. Our
        catalogue contains 2139 detections of 1314 discrete sources, including
        384 candidate ultraluminous X-ray sources (ULXs). We conservatively
        estimate the contamination of ULXs by background sources to be ~24 per
        cent. Columns 1-318 as in 3XMM-DR4, columns 319-384 as in RC3 (with LV
        values inserted into equivalent fields), columns 385-392 as from the
        NASA Extragalactic Database, columns 393-402 as from NBG (Tully &
        Fisher, 1988, Catalog of Nearby Galaxies. Cambridge Univ. Press,
        Cambridge), columns 403-423 generated for this catalogue.

    Note (1): Except in the case of a LV galaxy, for which the distance is given
      directly, DistRC3 (DISTANCE_RC3) is calculated from RV (RADIAL_VELOCITY)
      using Hubble's Law, with H0=75 km/s/Mpc. In the case of negative values, where
      galaxies are dominated by peculiar velocities, a negative distance will also
      result. Similarly, DistNED (DISTANCE_NED) is calculated from RVNED
      (VELOCITY_NED), also using Hubble's law.
      DistNBG (DISTANCE_NBG) is taken directly from the NBG catalogue.
      DistNEDD (DISTANCE_NEDD) is the average of values from the NED Distance
      Database, if the distance was obtained from Cepheid variables, the tip of the
      red giant branch, or Type Ia supernovae, in that order of precedence.
      DistBest (DISTANCE_BEST) thus contains the best value for the distance from
      these options, in the following order of precedence:
      DistNEDD (DISTANCE_NEDD), DistNBG (DISTANCE_NBG), DistNED (DISTANCE_NED),
      DistRC3 (DISTANCE_RC3).
      DistBest (DISTANCE_BEST) is used in any further calculation involving
      distance. See paper for more details.
