Catalog of equatorial coordinates and B‐magnitudes of the Kitab's part of the FON project

We present a catalog of stars with equatorial coordinates alpha and delta and B-magnitudes of stars for the Kitab's section of the FON project (FON-Kitab). The photographic plates of the FON project were exposed on the double telescope Double Zeiss Astrograph (DAZ, D/F = 40/300, 69 "/mm) at the Kitab observatory of the Republic of Uzbekistan. A total of 1963 plates, with size of 5.5 x 5.5 degrees (30 x 30 cm or 13,000 x 13,000 pixels) were digitized by Epson Expression 10000XL scanner with 1,200 dpi resolution. The reduction of plates was processed in the four astronomical organizations: Ulugh Beg Astronomical Institute (UBAI) of the Uzbek Academy of Sciences; the Mykolaiv Astronomical Observatory of the Ministry of Education and Science of Ukraine; the Walter Hohmann Observatory of Essen, Germany; and the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. The catalogue contains nearly 13.4 million stars and galaxies from 0 degrees to -20 degrees according to declination down to B = 17. (m)5 in the middle epoch of observation 1985.0. The coordinates of the stars and galaxies were obtained from the Tycho-2 catalogue, while B-magnitudes were determined in the system of photoelectric standards. The mean internal errors of the new catalogue for all objects were sigma(alpha delta) = 0. (")23 and sigma(B) = 0. (m)15 (for the stars in the range of B = 5(m) - 14(m), the errors are sigma(alpha delta) = 0. (")085 and sigma(B) = 0. (m)054 for the equatorial coordinates and the B-magnitudes, respectively). The convergence between the calculated and reference positions was sigma(alpha delta) = 0. (")042. The convergence with the photoelectric B-magnitudes is sigma(B) = 0. (m)16. External comparison with UCAC-4 based on 9,892,697 or 73.8% cross-identified objects yield sigma(alpha delta) = 0. (")26.
