“…The results of the performed work concerning the astrometric and photometric characteristics of the processing of photographic plates digitized by the Microtek ScanMaker 1000XL Plus scanner allowed to make the following conclusion: Within the precision of reduction of photographic plates the scanner is suitable for the performing of astrometric and photometric works for the terrestrial astronomy and in particular for the FON project Andruk, 2015b;Andruk, 2016a;Andruk 2016b;Relke, 2015;Yuldoshev, 2017). Errors of one measurement are 0.1 arc seconds for the equatorial coordinates and 0.04 m for the B-magnitudes.…”

“…The catalogue contains near 13.4 million stars and galaxies in the sky from 0• to -20• according to declination down to B = 17.5 m at the middle epoch of observation as 1985.0 year. The mean internal errors of the new catalogue for all objects are σ αδ = 0.23′′ and σ B = 0.15 m (for the stars in the range of B = 5 m − 14 m the errors are σ αδ = 0.085′′ and σ B = 0.054 m ) (Yuldoshev et al, 2017a;2017b).…”

FON project was expected a catalogue of stellar positions and B magnitude of Northern sky from combination six astronomical observatories of the former USSR were equipped with the same wide-angle astrographs: Goloseevo (Ukraine), Zvenigorod, Zelenchuk (Russia), Abastumani (Georgia), Kitab (Uzbekistan) and Hi-sorAO (Tajikistan). This paper has been presented the comparison results of three catalogues (FON-KIEV, FON-KITAB and FON-DUSHANBE) were received as result of scanning and astrometric reduction of photographic plates in the coordinate system of Tycho-2 catalogue. The data of zero zone (from-2 to 2 degrees of declination) from the mentioned catalogues was used during the research. The number of common objects after cross-match of catalogues with a circular search window equals to 1.5 arc seconds was more than 500 thousands. The estimation of random accuracy of stars positions from the mentioned catalogues was performed by the Wielen method. Final dispersions were calculated for every sub-range of magnitudes. The stars with individual differences of position and magnitude that exceed three standard deviations were rejected. The data from catalogues РМА was used for estimation of the systematic errors. It is obvious that the internal estimates of position accuracy of stars in the compared catalogues are low in one or all catalogues, and additional research is required. Analysis of the behavior of the systematic differences and standard deviations of the stellar positions of these catalogues have shown that there are a big values reaching 1 arcsec only in small sky regions. However, the internal estimation of accuracy that presented in catalogues is well matched with the systematic differences and standard deviations in the other sky regions.

ABSTRACT. Catalogue of 13.4 million stars down to 17.5 m 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 the Double Astrograph of Zeiss (DAZ, D/F = 40/300, 69"/mm) from 1981 to 1996. Digitization of these plates was made by using Epson Expression 10000XL scanner with the 1200 dpi resolution. Catalogue includes objects from the 1963 plates in declination zone between -20° and +2° for middle epoch 1984.97. The equatorial coordinates of objects were determined in the Tycho-2 reference system and the B-magnitudes in the system of the photoelectric standards. Five participants from Uzbekistan, Germany and Ukraine have taken part in the processing of the digitized images. The average internal accuracy of the catalogue for one observation are 0.23" and 0.15 m for the equatorial coordinates and Bmagnitudes respectively. For the stars brighter than 14 m the errors are 0.09" and 0.05 m respectively. The analysis of the catalogue and its comparison with the several astrometric catalogues was done.
