What can BeppoSAX do about the 2-10keV cosmic background? A progress report.
Abstract
We report the current status of the analysis of the MECS background using the entire dataset of the BeppoSAX Science performance Verification Phase. We have collected 360ks of dark Earth instrumental background, 470ks of bright Earth background and 1100ks of blank field data. We are attempting to model the instrumental background in terms of its various components (in particular the spatial modulation of the residual contamination by the built-in Fe calibration sources), and then use this model, and the information on the vignetting and the PSF to derive the cosmic background in the 2-10keV range.
