... The procedure involves fitting the point-spread function to one or more sources by a least-squares fit. The background can either be determined in the fit, or a fixed background value. ... For more details of the PSF fitting method please refer to the documentation on the SAS task omphotom . The weighting scheme used in the fitting can be either 1/pixel variance or 1 (equal weights). For information about how the latter is done, please refer to the documentation for the SAS task omphotom . ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... 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). ...
