Description
Catalog of 90 astrometric positions of Pluto 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, Astronomical Observatory of the Kyiv Shevchenko National University, Research Institute Mykolaiv Astronomical Observatory and Baldone Observatory of the University of Latvia in 1961-1996. Astronegatives have been digitized with Epson Perfection V750 Pro and Epson Expression 10000XL commercial scanners in 16-bit grayscale with a resolution of 1200 dpi. (O-C) residuals obtained from the comparison with JPL PLU055/DE433 ephemeris are 0.09 ... 0.14 arcsec.
