| Abstract: | The catalog of equatorial coordinates α and δ and B-magnitudes of stars of the northern sky (from–4° to +90°) was created as a part of the FON project at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. The data accumulated in the Joint Digital Archive of the Ukrainian Virtual Observatory were used. The total number of processed plates is 2260. Astronegatives were digitized with Microtek ScanMaker 9800XL TMA and Epson Expression 10000XL scanners in the 1200 dpi scanning mode. The majority of plates have a size of 30 × 30 cm (13000 × 13000 pixels). The catalog contains the data on 19451751 stars and galaxies with B ≤ 16.5m at the epoch of 1988.1. The coordinates of stars and galaxies were obtained in the Tycho-2 reference system, and B-magnitudes were determined in the system of photoelectric standards. The mean internal errors of the catalog are σαδ = 0.23″ and σB = 0.14m for all objects or σαδ = 0.10″ and σB = 0.07m for stars in the B = 7m–14m range. The convergence between the catalog and Tycho-2 is characterized by the following values: 0.06′′ and 0.15m. The mean-square difference in coordinates from the catalog and from UCAC-4 is σαδ = 0.30′′ (18 742 932 objects, or 96.36% of stars and galaxies, were cross-identified). |
