Abstract:
Catalogs of 145 astrometric positions of Uranus and 4 its moons U1-U4
and 62 positions of Neptune and Triton have 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 1963-1990. 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 for
the precise positional determination. The internal positional accuracy
of the reduction is 0.04-0.25" for both coordinates and 0.21-0.65m
for photographic magnitudes of the Tycho-2 catalog. Gallery of plate
