XMM-Newton Science Analysis System . ... Light of stars outside the telescope field of view may reach the RGS focal plane after reflections on the front side of the gratings. Optical light may also be reflected on the back surface of the gratings; before launch the exact magnitude of this effect is not known. Regions around the pointing direction from which light could be reflected on the RGS focal plane are called avoidance fields . ...
