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 . ...

... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...
