Abstract:
A catalog of 1399 astrometric positions of Saturn's moons S2-S9
has been compiled with Tycho-2 as a reference frame from photographic
observations obtained at the Main Astronomical Observatory, National
Academy of Sciences of Ukraine, in 1961-1990. Astronegatives have
been digitized with an Epson Expression 10000XL commercial scanner in
16-bit grayscale with a resolution of 1200 dpi. Reduction has been
performed in the LINUX-MIDAS-ROMAFOT software supplemented with
additional modules. The internal positional accuracy of the reduction
is 0.09...0.23" for both coordinates and 0.27...0.37m for the
photographic magnitudes of the Tycho-2 catalog. Gallery of plate
