| # Detailed Description of IX/58 : 2SXPS Swift X-ray telescope point source catalogue (Evans+, 2020) |

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 present the 2SXPS (Swift-XRT Point Source) catalog, containing
        206,335 point sources detected by the Swift X-ray Telescope (XRT) in
        the 0.3-10 keV energy range. This catalog represents a significant
        improvement over 1SXPS, with double the sky coverage (now
        3,790deg2), and several significant improvements in source detection
        and classification. In particular, we present for the first time
        techniques to model the effect of stray light - significantly reducing
        the number of spurious sources detected. These techniques will be very
        important for future, large effective area X-ray mission such as the
        forthcoming Athena X-ray observatory. We also present a new model of
        the XRT point spread function, and a method for correctly localising
        and characterising piled up sources. We provide light curves - in four
        energy bands, two hardness ratios and two binning timescales -- for
        every source, and from these deduce that over 80,000 of the sources in
        2SXPS are variable in at least one band or hardness ratio. The catalog
        data can be queried or downloaded via a bespoke web interface at
        https://www.swift.ac.uk/2SXPS, via HEASARC, or in Vizier (IX/58)

    Description:
        The 2SXPS catalogue is a point-source catalogue built from all
        Swift-XRT Photon Counting mode data of at least 50 s in duration
        gathered prior between 2005 Jan 01 and 2018 August 01. It contains
        positions, fluxes, spectral details, variability information and a
        flag indicating the reliability of the detection for 206,335 objects.
        Various values (e.g. the count rates) are given in 4 bands:
        Total = 0.3-10 keV
        Soft = 0.3-1 keV
        Medium = 1-2 keV
        Hard = 2-10 keV
        The source detection was performed in each of these bands
        independently, and the results combined to give this final catalogue.

    Note (1): A value of -1 indicates that the source position was never fully
       in the field of view.
    Note (2): Swift Mission Elapsed Time (MET) is seconds (TT) since
       2001 Jan 01 00:00:00
    Note (3): Detection flags areas follows:
       0 =  Good
       1 =  Reasonable
       2 =  Poor
      +4 =  The source position is consistent with that of a known extended source
      +8 =  The source is likely an alias of a badly-fitted piled up source
     +16 =  The source lies in a region marked as contaminated during the visual
             screening
    Note (4): Field flags are bitwise with the following warnings bits:
       0 (val=1): Field contains stray light.
       1 (val=2): Field contains diffuse emission or artifacts.
       2 (val=4): Field contains stray light that could not be adequately modelled.
       3 (val=8): Field contains a bright, pile up source which was not properly
                   fitted in some bands.
    Note (5): Optical loading occurs when a high flux of optical photons deposits
       sufficient charge in the XRT to produce spurious X-ray events. See
       https://www.swift.ac.uk/analysis/xrt/optical_loading.php
       If this is 0 there is no warning, otherwise there is a nearby optical source
       brighter than the level at which optical loading becomes a concern; the value
       indicates how many magnitudes brighter than that level the source is
    Note (6): PVAR

    Note (7): Provenance of the summary spectral fit as follows:
      0 = fixed spectrum
      1 = HR-derived
      2 = fitted spectrum
    Note (8): Some of the properties derived from spectral fitting may have error
      values with the wrong sign, i.e.  positive values for the negative errors and
      vice versa. These indicated cases where xspec was unable to properly determine
      the uncertainty on the parameter.
