... epevents (epevents-6.43) [xmmsas_20080701_1801-8.0.0] . ... A pattern analysis is made which yields four distinctive parameters: the number of pixels in the structure, the running pattern number within a frame, the pattern orientation (zero for singles and unresolved patterns; otherwise a three digit code, with the last digit specifying the orientation of the pattern and the first two the position of the pixel on the pattern ) and the distance (in pixels ) to neighbouring ...

Next: *upspecrdf, downspecrdf* - Transform Up: Spectral Analysis Previous: *grid_plot* - Plot Results . The conversion of count rate to flux depends on the intrinsic spectrum of the source, so xflux must be used in conjunction with fit . Fit generates a table of the best fit intrinsic spectrum ( _int.tab extension). xflux uses this table to calculate either the integrated flux between two energy limits or the flux density at a specific energy. ... This produces ``..._obs.tab'' file. ...

... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...

... Use of ORIENT, PATTERN-ORIENT, and POS TARG . ... HST Overview . Overview . ... Observers who use the PATTERN-ORIENT and POS TARG requirements on the same exposure should be aware that there is a bug in RPS2, that executes the latter in the frame of the former. ... You can improve the schedulability of the observations by using PATTERN-ORIENT instead, and CHOP- and DITH- SIZE chosen so that the distance between adjacent field centers is 0.5sqrt(2) times the camera dimension. ...

... The uniform flux density in each pattern is 100 units per pixel. ... In order to illustrate the case of a point spread function which in one dimension is extremely undersampled, a delta function is also included (the lower left hand pattern in BARS). ... The coordinates of the left hand pixel of the delta function are again (42,52), and the other patterns have lower left hand pixels distant by 10, 20 and 34 pixel units. ... Uniform flux density of 100 units/pixel is used. ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ...
