Abstract

An automated reduction method for determining field distortion common to all plates based on a black-adjustment method proposed by Stock (1981) is demonstrated on the Paris Zone of the Astrographic Catalog. It is shown that the FK5 is suitable as the only reference source for zone catalogs.
