Investigation of the Microtek Scanmaker 1000XL Plus Scanner of the Institute of Astrophysics of the Academy of Sciences of the Republic of Tajikistan
Andruk, V.; Yuldoshev, Q.; Mullo-Abdolov, A. +3 more
This work was done to estimate the accuracy of the processing method of photographic plates and the detailed study of the Microtek ScanMaker 1000XL Plus scanner, which plans to be used for the digitizing of about 1600 photographic plates of the Astrophysics Institute of the Academy of Sciences of the Republic of Tajikistan (Dushanbe) recorded for …
Catalogue of Coordinates and B-Magnitudes in -20° - +2° Zone Based on the Ulugh Beg Astronomical Institute Part of the Fon Project
Ehgamberdiev, Sh. A.; Andruk, V. M.; Muminov, M. M. +5 more
Catalogue of 13.4 million stars down to 17.5m was obtained in 2017 by using plates from the Kitab Observatory of Ulugh Beg Astronomical Institute (UBAI) of the Uzbek Academy of Sciences. Kitab's part of Photographic Sky Survey (Russian abbreviation is FON, in next contexts) project include more than 2600 photographic plates, exposed on …
Catalogue of Astrometric Positions of Jupiter's Outer Satellites on Photographic Observations in Mao NAS of Ukraine in 1987-1993
Yizhakevych, O.; Andruk, V.; Pakuliak, L.
The catalog of 33 topocentric positions of Jupiter's moons J6, J7, J8 has been created on photographic observations made in MAO NASU in 1987-1993. Positions are referred to the system of TYCHO-2 using the program package INUX/MIDAS/ROMAFOT. The comparison of observed positions was made online with their theoretical data of IMCCE (www.imcce.fr/sat).
Determination of the Galaxy Cluster Orientation Using X-Ray Images by FOCAS Method
Tugay, A. V.; Shevchenko, S. Yu.
In our work we considered orientations of bright X-ray halos of the galaxy clusters (mainly Abell clusters). 78 appropriate clusters were selected using data from Xgal sample of extragalactic objects in XMM-Newton observation archive. Position angles and eccentricities of these halos were calculated applying FOCAS method. No privilegd orientations…
Accuracy of Mykolaiv Asteroid Observations with Different Reference Catalogues
Maigurova, N. V.; Pomazan, A. V.; Bodryagin, D. V. +1 more
The results of astrometric reductions of main belt asteroid observations with usage of 3 different reference catalogues are presented. The high precision catalogs CMC15, UCAC4 and GAIA DR1 were used as reference catalogues for calculation asteroid equatorial coordinates. The asteroid observations were carried out at KT-50 telescope of the RI "MAO"…
Astronomical Image Processing for High-Accurate Astrometry Data
Akhmetov, V. S.; Dmytrenko, A. M.
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 …
Supervised Automatic Identification of Extragalactic Sources in the WISExSUPERCOSMOS Catalogue
Khramtsov, V.; Akhmetov, V.
We present new catalogue of ∼8,500,000 extragalactic objects as a result of automatic classification of WISE and SuperCOSMOS (SCOS) cross-identification product. The main goal is to create a set of candidates in extragalactic objects due to colour (photometric) features through machine learning techniques. Extragalactic sources were separated from…
