202. Accuracy of World positional CCD observations of the numbered minor planets
. Authors . Problem . Method . Advises . Contact Analysis of an accuracy of CCD asteroid observations carried out by professional and amateur astronomers . An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400
