The level of accuracy for digitizers dedicated to astrometry

Abstract

We discuss different parts of the digitization process and their influence on the final measurement for astometry. The goal is to define what could be the adapted digitizer components providing the required astrometric accuracy. We base our discussion on the use of the DAMIAN scanner with USNO photographic plates. Thus we evaluate intrumental parameters and their influence such as the stability and the position repeatability, with optical parameters such as the camera optical distortion and repeatability.
