Derivation of preliminary IBIS response matrices with the INTEGRAL simulator
Abstract
We have used the IBIS Simulator to produce preliminary response matrices for the ISGRI and PICsIT detectors in order to help understanding their scientific performances before the calibration results are available. The derived matrices, in a format compatible with the XSPEC spectral analysis package, have been tested by fitting simple models and then used to analyze simulations of astrophysical sources with more complex spectra.
