Method for estimating the accuracy of
astrometric (rectangular coordinates) and photometric (diameters and magnitudes) characteristics of commercial scanners is proposed and applied. The method is
demonstrated using an example of processing of sequential scans of plates, which were exposed with different
telescopes and then digitized with resolution of 1200 dpi with several Epson scanners. Scanning operations were
carried out in various observatories as part of development of the database of photographic observations for Virtual
Observatories (Vavilova, 2012). Errors of studied scanners are equal to σx, y = ± 0.02-0.06px and σm = ± 0.015-0.024
mag for astrometry and photometry, respectively.
