| # Detailed Description of IX/43 : 1SXPS Swift X-ray telescope point source catalogue (Evans+ 2014) |

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 1SXPS (Swift-XRT Point Source) catalogue of 151,524
        X-ray point-sources detected by the Swift-XRT in 8 years of operation.
        The catalogue covers 1905 square degrees distributed approximately
        uniformly on the sky. We analyze the data in two ways. First we
        consider all observations individually, for which we have a typical
        sensitivity of ~3e-13 erg.cm-2s^-1` (0.3-10 keV). Then we co-add
        all data covering the same location on the sky: these images have a
        typical sensitivity of ~9e-14 erg cm-2s-1 (0.3-10 keV). Our sky
        coverage is nearly 2.5 times that of 3XMM-DR4, although the catalog
        is a factor of ~1.5 less sensitive. The median position error is 5.5"
        (90% confidence), including systematics. Our source detection method
        improves on that used in previous XRT catalogues and we report >68,000
        new X-ray sources. The goals and observing strategy of the Swift
        satellite allow us to probe source variability on multiple timescales,
        and we find ~30,000 variable objects in our catalog. For every source
        we give positions, fluxes, time series (in four energy bands and two
        hardness ratios), estimates of the spectral properties, spectra and
        spectral fits for the brightest sources, and variability probabilities
        in multiple energy bands and timescales.

    Description:
        The 1SXPS catalogue is a point-source catalogue built from all
        Swift-XRT Photon Counting mode data of at least 100-s in duration
        gathered prior to 2012 October 12 (Swift was launched in 2004
        November). It contains positions, fluxes, spectral details,
        variability information and a flag indicating the reliability of the
        detection for 151,524 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): Detections flags are:
          0 = good
          1 = reasonable
          2 = poor
         +8 = good(8), reasonable(9), poor(10) in a region marked as
              containing artifacts
        +16 = good(8), reasonable(9), poor(10) in a region marked as
              containing diffuse emission
    Note (2): Field flag takes the values:
          0 = OK
          1 = has artifacts
          2 = has diffuse emission
    Note (3): according to the Pearson's {chi}-square test

    Note (4): provenance of the summary spectral fit:
          0 = fixed spectrum
          1 = HR-derived
          2 = fitted spectrum
    Note (5): a value of -1 indicates indicates that the source was never in the
        field of view, i.e. was detected and localized via the PSF wings.
    Note (6): In a small number of cases where the Bayesian approach was used
        to derive the parameter, the mean value lay outside the 1-{sigma}
        confidence interval. In these cases the positive error may be
        negative, and the negative error may be positive.
    Note (7): a value of -1 for positive error or +1 for negative error means
         that the error was unconstrained.
