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 International Gamma-Ray Astrophysics Laboratory (INTEGRAL)
        continues to successfully work in orbit after its launch in 2002. The
        mission provides the deepest ever survey of hard X-ray sources
        throughout the Galaxy at energies above 20keV. We report on a
        catalogue of new hard X-ray source candidates based on the latest sky
        maps comprising 14yr of data acquired with the IBIS telescope onboard
        INTEGRAL in the Galactic Plane (|b|<17.5°). The current catalogue
        includes in total 72 hard X-ray sources detected at S/N>4.7{sigma} and
        not known to previous INTEGRAL surveys. Among them, 31 objects have
        also been detected in the on-going all-sky survey by the BAT telescope
        of the Swift observatory. For 26 sources on the list, we suggest
        possible identifications: 21 active galactic nuclei, two cataclysmic
        variables, two isolated pulsars or pulsar wind nebulae and one
        supernova remnant; 46 sources from the catalogue remain unclassified.

    Description:
        For this work, we selected all publicly available INTEGRAL data from
        2002 December to 2017 March (spacecraft revolutions 26-1790).

        In total, we obtained 124 727 ScW images covering the whole sky,
        comprising ~220Ms of the effective (dead time-corrected) exposure. For
        the purposes of this work we selected 79234 ScWs (~130Ms) within the
        GP (|b|<17.5°). Following Krivonos et al. (2012, Cat.
        J/A+A/545/A27) we constructed six overlapping 70°x35°
        Cartesian projections centred at the GP (|b|=0°) and Galactic
        longitudes l=0°, ±50°, ±115° and l=180°.

    Note (1): The source is located in the region of high systematic noise, and its
      measured flux should be treated with caution (noise=1).
    Note (2): General astrophysical type of the object as follows:
      AGN     = active galactic nucleus
      SNR/PWN = supernova remnant/pulsar wind nebula
      CV      = cataclysmic variable
      PSR     = isolated pulsar or pulsar wind nebula

      The question mark indicates that the specified type is not firmly determined,
        so it should be confirmed.
