A fraction of the XMM-Newton EPIC FOV is obscured by the dysfunctional (i.e. bad) pixels, dominated by the CCD gaps, which complicates the analysis of extended X-ray sources. Before SAS version 17.0.0 the only standard option for attempting the recovery of the obscured flux was to scale the measured flux by the fraction of the obscured detector area. This is accurate only in the very limiting case of an extended source with a uniform spatial flux distribution.
