Catalog of positions and B magnitudes of stars of the part of Kitab northern sky survey (FON) project

Abstract

The works of processing of Kitab's plates of FON project was completed. It was used 1963 plates. The catalogue of equatorial coordinates and B-magnitudes of 13 413 268 stars and galaxies up to B ≤ 17.5m for the epoch 1984.97 was compiled. The Epson Expression 10000XL scanner was used for digitization with the mode 1200 dpi, the size of plates are 30*30 cm or 13 000*13 000 px. The coordinates of stars and galaxies were obtained in the Tycho-2 reference system, and B-value in the system of photoelectric standards. The internal accuracy of the catalog for all objects is σαδ = 0.23" and σB = 0.15m (for stars in the range of B = 5m...14m errors areσαδ, HB = 0.085" and σB = 0.054m). Convergence between the calculated and reference positions is σαδ = 0.042", and the convergence with photoelectric stellar B-magnitudes is σB = 0.16m. External accuracy from the comparison with UCAC-4 is σαδ = 0.26" ( 9 892 697 or 73.75 % stars and galaxies were cross identified).
