Astrometric and photometric processing of Pluto digitized photographic observations 1961-1996
Abstract
A catalog of equatorial coordinates and magnitudes of Pluto for the period 1961-1996 has been derived from digitized photographic observations from the combined digital archive of Ukrainian Virtual Observatory and the Institute of Astronomy of University of Latvia. Improvement of software processing of digitally scanned images allowed single images to be extracted from multiple exposures of Pluto images represented on a single astronegative. As a result of the new aproach 22 new coordinate measurements of Pluto observations have been added to the 80 already in this catalog. Comparison has been made with the JPL DE431 ephemeris and the results analyzed.
