ASTRONOMICAL IMAGE PROCESSING FOR HIGH-ACCURATE ASTROMETRY DATA
Journal Title: Odessa Astronomical Publications - Year 2017, Vol 30, Issue
Abstract
This article presents the main results of the initial processing of some of the astronomical images obtained from the archive of the digitized photographics survey of the whole sky SuperCOSMOS. Using of the median filtering and gausian convolution procedure with the adaptive kernel allows to carry out the initial processing of astronomical images without calibration frames. After the initial processing, the photocenters of the celestial objects were identified by various methods. It has been concluded that after the use of the mathematical methods for the initial processing of the digitized photographics images, the position of objects is calculated with a higher random and systematic precision.

THE DEPENDENCE OF ON- AND OFF-STATE GENERATIONS IN CLASSICAL MICROQUASARS FROM THE DISK DENSITY. 3-D NUMERICAL HYDRODYNAMICAL SIMULATIONS OF THE HIGH AND LOW MASS ACCRETION RATE IN ACCRETION DISK IN MICROQUASAR CYG X-1
In the present work we have computed and have compared the on- and off- generations in low and high mass accretion rate accretion disks. The comparison shows that in the case of low mass accretion rate in disk (10−10 sola...
