Astrometry of the Plates of the DWA Digitized with the MICROTEK SCANMAKER 9800XL TMA Scanner

Andruk, V.; Golovnya, V.; Yatsenko, A.

A detailed testing of the Microtek ScanMaker 9800XL TMA scanner aimed at large-scale plates (300 × 300 mm and larger) digitization has been undertaken. The evaluation of the accuracy of star image centering and darkening determined from the newly developed method in MIDAS/ROMAFOT environment has been carried out from the comparison of digitized im…
