Abstract: We compiled the catalogue of 59 equatorial coordinates and magnitudes of the Pluto — Charon system for the interval from 1961 to 1990 which is based on digitized photographic data of the Joint Digital Archive of the Ukrainian Virtual Observatory. They include observations of five telescopes of three Ukrainian observatories. We successfully applied the developed software and methodics for skan processing. The parametric processing model was analyzed. The average accuracy for the equatorial coordinates of Tycho-2 reference stars on the digitized plates of the five telescopes is ±90 mas. The mean error of Tycho-2 BT magnitudes is ±0.32m. The Pluto positions were compared with the ephemeris JPL PLU43-DE431. |
