Plot description: Histogram of the source flux averaged over s/c orbit (see lightcurve on the left). The flux bin [1,5] mCrab contains counts from range [-5,5] mCrab. The flux measurements with error >5 mCrab were dropped.
Plot description: The blue data points show source flux over one s/c orbit (3 days). The all time-averaged flux and corresponding 1σ errors are shown in red. The star symbol is shown when flux error is greater than 5 mCrab and detection significance is less than 3σ.

  1. Time-averaged source flux in mCrab units. A flux of 1 mCrab corresponds to 1.43e-11 erg/s/cm2 for a source with a Crab-like spectrum.
  2. Source flux was measured on the map averaged over the indicated spacecraft revolution.
  3. General astrophysical type of the object. LMXB (HMXB) - low- (high-) mass X-ray binary, AGN - active galactic nucleus, SNR/PWN - supernova remnant/pulsar wind nebula CV - cataclysmic variable, PSR - isolated pulsar or pulsar wind nebula, SGR - soft gamma repeater, RS CVn - coronally active binary star, SymbStr - symbiotic star, MolCld - Molecular cloud, Cluster - cluster of galaxies.
  4. Additional notes and/or alternative source names. References are mainly provided for new sources and are related to their discovery and/or nature.
Notes on catalog
  • The positional accuracy of sources detected by IBIS/ISGRI depends on the source significance. The estimated 68% confidence intervals for sources detected at 5-6, 10, and > 20 standart deviations are 2.1, 1.5, and < 0.8 arcmin, respectively.
