| Popis: | Catalogue of star positions and B-magnitudes based on UkrVO Joint Digital Archive has been created in 60-degree declination zone of FONAK(FON) observational program as the first attempt to use the commercial scanners for astrometri c purposes. The height of zone is 8 degree, number of involved plates is 120. Digital images of plates were obtained using Microtek ScanMaker 9800XL TMA commercial scanner, with plate resolution 1200 dpi, linear dimensions 13,000x13,000 px for plates 30x30cm. The catalogue includes 1, 263, 932 stars and galaxies down to B 16.5 mag at the epoch 1984.76+/-0.50. Positions of objects are in TYCHO-2 reference frame, B-magnitudes in the system of photoelectric standards. The internal accuracy for all objects on both coordinates RA,DEC is +/-0.26 arcsec.The accuracy of B magnitudes determination is +/-0.17 mag, except stars in the B-interval 8-13 mag having the positional errors +/-0.13 arcsec and photometric ones +/-0.11 mag. The convergence of star positions with TYCHO-2 system is +/-0.06 arcsec on both coordinates(based on 93,925 stars), the convergence with photoelectric standards system is +/-0.16 mag (based on 4,458 stars). External comparison with UCAC-4 gives the positional errors +/-0.34 arcsec based on 1, 099, 005 cross-identified objects. Comment: 19 pages, 10 figures, 5 tables, 20 references, presented at 14-th International Gamow Conference-School, 17-23 August, 2014, Odessa, Ukraine |
