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.
