The standard designation for the source. Sources discovered by INTEGRAL have been given names using the IGR prefix.
This parameter is a flag which can have the following non-blank values:
a = 4U0352+30 in 1st IBIS/ISGRI catalog (Cat1); b = Values derived from staring observations during revolutions 50, 154 and 203; c = Detected during revolution 139; d = Cannot recover fluxes due to proximity to 4U0919-54; e = Detected during revolution 203; f = A1145.1-6141 in Cat1; g = Position taken from 1E catalog, due to blending with 2E1145.5-6155; h = Position taken from 1E catalog, due to blending with 2E1145.1-6141; i = 4U1516-569 in Cat1; j = IGR J16195-4945 in Cat1; k = Triangulum Australis; l = IGR J16393-4643 in Cat 1; m = PSR J1649-4349 in Cat1; n = Equally well associated with NGC 6221, also Sy2; o = Detected during revolution 171; p = EXMS B1709-232 in Cat1; q = Tentative association with NGC6334; r = IGRJ17254-3616 in Cat1; s = Detected during revolution 120; t = 1E1740.7-2943 in Cat1; u = M1741-293 in Cat1; v = Within 1.1' of Sgr A*; w = Fluxes unreliable due to blending in final mosaic, see Section 3.6; x = Detected during revolution 175; y = IGR J18027-2016 in Cat1; z = HESS source (SNR/PWN?); A = 4U1849-31 in Cat1; B = Detected during revolution 189; C = IGR J19140+098 in Cat1; X = new detection since first catalog.
The Right Ascension of the high-energy source in the selected equinox. This was given in J2000.0 coordinates and to a precision of 0.001 degrees in the original table.
The Declination of the high-energy source in the selected equinox. This was given in J2000.0 coordinates and to a precision of 0.001 degrees in the original table.
The Galactic Longitude of the high-energy source.
The Galactic Latitude of the high-energy source.
The positional error of the high-energy source, in arcminutes, expressed as the radius of the 1-sigma error circle.
This parameter is set to '<' if the associated soft-band flux of the particular source is an upper limit rather than a detection.
The flux of the high-energy source in the soft energy band (20-40 keV), in units of milliCrab (mCrab). Appropriate conversion factors for this band are 10 mCrab = 7.57 x 10^-11 erg/cm^2/s = 1.71 x 10^-3 photons/cm^2/s.
The uncertainty in the 20-40 keV flux, in mCrab.
This parameter is set to '<' if the associated hard-band flux of the particular source is an upper limit rather than a detection.
The flux of the high-energy source in the hard energy band (40-100 keV), in units of milliCrab (mCrab). Appropriate conversion factors for this band are 10 mCrab = 9.42 x 10^-11 erg/cm^2/s = 9.67 x 10^-4 photons/cm^2/s.
The uncertainty in the 40-100keV Flux, in mCrab.
The maximum significance of the high-energy source, quoted either in the band specified by the significance_flag parameter, or, if the latter is blank, in one revolution.
This parameter is a flag which, if populated, indicates the detection band, in keV, to which the quoted maximum significance applies. If left blank, the quoted significance is for one revolution.
The corrected on-source exposure, in seconds (s). This parameter was given with a precision of kiloseconds in the original, as-published table.
The astrophysical type of the high-energy source. The following abbreviations have been used:
A = atoll source (neutron star) AGN = active galactic nucleus AXP = anomalous X-ray pulsar B = burster (neutron star) Be = B-type emission-line star Bh = black hole (confirmed mass evaluation) BHC = black hole candidate Cluster = cluster of galaxies CV = cataclysmic variable D = dipping source G = globular cluster X-ray source HMXB = high-mass X-ray binary LMXB = low-mass X-ray binary Mol cloud = molecular cloud NS = neutron star PSR = radio pulsar PWN = pulsar wind nebula QSO = quasar SGR = soft gamma repeater SNR = supernova remnant Sy = Seyfert galaxy Symb = symbiotic star T = transient source U = ultrasoft source XB = Galactic X-ray binary XP = X-ray pulsar Z = Z-type source (neutron star)
