“…a day. We simulated such an observation in the energy range 40-80 keV assuming sources are at their average brightness level as measured with the SIGMA/GRANAT telescope [8] during its 7 year long galactic center survey ( [7,9]) and adding a contribution also from 4U 1700-37, a hard X-ray high mass binary, at a level about 1/2 lower than the peak flux value detected by SIGMA [4]. We then applied sky image reconstruction and cleaning algorithm as described in the previous section.…”

The Imager on Board Integral Satellite (IBIS) is the imaging instrument of the INTEGRAL satellite, the hard-X/soft-gamma ray ESA mission to be launched in 2001. It provides diagnostic capabilities of fine imaging (12' FWHM), source identification and spectral sensitivity to both continuum and broad lines over a broad (15 keV-10 MeV) energy range. It has a continuum sensitivity of 2 10 −7 ph cm −2 s −1 at 1 MeV for a 10 6 seconds observation and a spectral resolution better than 7 % at 100 keV and of 6 % at 1 MeV. The imaging capabilities of the IBIS are characterized by the coupling of the above quoted source discrimination capability with a very wide field of view (FOV), namely 9 • × 9 • fully coded, 29 • × 29 • partially coded FOV. We present simulations of IBIS observations of the Galactic Center based on the results of the SIGMA Galactic Center survey. They show the capabilities of this instrument in discriminating between different sources while at the same time monitoring a huge FOV. It will be possible to simultaneously take spectra of all of these sources over the FOV even if the sensitivity decreases out of the fully coded area. It is envisaged that a proper exploitation of both the FOV dimension and the source localization capability of the IBIS will be a key factor in maximizing its scientific output.
