摘要:We consider the complete sample of AGN detected by INTEGRAL/IBIS in the 20–40 keV band and extracted from the the 3rd IBIS survey [9]. The sample includes all sources detected above 5.2s , can be used to provide an insight into the population of hard X-ray selected AGN. For the entire sample, we study the hard X-ray (20–100 keV) spectral properties, comparing them with SWIFT/BAT 58 months data: we give information on spectral and flux variability, average spectral shape and BAT/IBIS cross-calibration constant. We also provide an example of how the hard X-ray spectra can be used to constrain some important spectral parameters, such as reflection and/or high energy cut-off.
