... The main field of our team interests is the researching of galaxy clusters as well as single nearby galaxies. The galaxies and galaxy clusters, being gravitationaly bound and reliably distinguishable systems, allow us to determine their global physical characteristics. At the same time they are integrated as elements into higher level spatial structures or systems. ... Вack to main homepage . ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...

... DBE is used to specify the personality to use in a digital backend that is based on an FPGA. ... RDBE_PFB is the original polyphase filter personality developed by Haystack for the RDBE digital backend ( DAR=RDBE in the station catalog). It is restricted to 16 baseband channels of 32 MHz bandwidth each, lower sideband, with frequencies of 1024-16-N*32 MHz, where N is an integer between 0 and 15. ... Those baseband channels can be as wide as 128 MHz so the full input bandwidth can be covered. ...

... Up: Algorithms . ... Iterative algorithms with non-linear constraints are very attractive in image reconstruction with only a few strip-integrated projections. We present research into various versions of the iterative CLEAN algorithm for the solution of this problem. ... where is the object brightness distribution, is the fan (dirty) beam, and is the dirty (summary) image. ... We carried out the study of TC-CLEAN applied to image reconstruction with few projections. ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

... The most precisely determined characteristic for accreting neutron stars (NS's) is their period. ... Period changes show fluctuations. ... Some applications of stochastic processes in astrophysics especially in accreting systems were discussed in Lipunov (1987),Hoshino Takeshima (1993) and Lipunov (1992).In Hoshino Takeshima (1993) the authors, using simple models of MHD turbulence, try to explain aperiodic changes in X-ray luminosity of X-ray pulsars. ... Here, -constant angular momentum. ...

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...

The azimuth encoder rack gear is mounted on the inside of the azimuth ring girder. The azimuth encoder turns on this gear as the azimuth moves 0 to 720 degrees. ... The software assumes that this arc length along the encoder rack gear is correct (at a constant radius of 127/2 feet). The error in the radius of the rack gear becomes an azimuth error. To measure the error in the azimuth encoder rack gear, jon hagen built a proximity sensor. ... To compute the az encoder runout error: . ...

... 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 forseeable saturation of scaling CMOS devices the electron spin att racts much attention as a complement or even a replacement of the electron charge in digital information processing. ... Because of these properties the electron spin lifetime in silicon is long, which makes silicon perfectly suited for spin-driven applications. ... It is straightforward to apply the same techniques to obtain a spin lifetime above 1ns making silicon films and fins perfect spin interconnects. ... Wien - New York...
