The FON Astrographic Catalogue (FONAC)
Listed in IVOA Registry (Virtual Observatory)
The FONAC is a catalogue of positions, proper motions and photometric data for 2,008,383 of Astrographic Catalogue (AC) stars covering the sky between declinations +90 and -2 degrees.
Description
The average epoch of positions is 1988.19. The catalogue is based on the measurements of more then 1700 plates which were taken with the wide-angle astrograph of the Main Astronomical Observatory (MAO) in Kiev within the FON (Photographic Survey of the Northern Sky) project.
The AC data were used both as the input catalogue for measuring machine PARSEC (Programming Automatic Radial-Scanning Coordinatometer) and as the first epochs for determination of proper motions of stars. The ACT Reference Catalogue was applied for the reductions of positions and B magnitudes of stars, the GSC1.1 was used for determination of (B-V) values, and the USNO R-magnitudes were used for determination of (B-R) values.

The estimated precision is 0.2 arcseconds for the positions, 3 mas/yr for the proper motions, and 0.18mag for the photometry.
