... As sketched in Fig. 3, registered images are influenced by fractions of the original signal from outside the domain of measured data. ... Inner Region . ... A rigorous solution which completely avoids the boundary problem is the extension of the region of restoration by the extent of the point spread function. If the extent of the measured data is 512 512 and the extent of the point spread function is 256 256, the extent of the region of the restoration should be (512 + 256) (512 + 256) = 768 768. ...

... 739C As one part of a program to detect complete samples of active extragalactic objects, the 3.36x10^-3 sr field centered on alpha=12h04min, delta=+11deg30' (1950.0) was mapped with the Very Large Array at 1411MHz. Sixty-seven maps cover this field so that no point is more than 15arcmin from the nearest map center. ... The rms map noise is 0.030 + 0.001 mJy, and the resulting source list is complete to a map peak flux density S_p = 0.2 mJy within 25 arcmin of the field center. ...

SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ... The main types of the singular points are the node, the focus, the center, and the saddle. ... Singular point of the focus type in the solar chromosphere. ...

... 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. ...

... 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. ...
