Zusammenfassung:An account is given of an updated AGK3 with improved proper motions derived from the Palomar 'Quick V' survey. It is judged that the astrometric potential of large-scale Schmidt plates can be realized via the subplate technique, followed by integration with the results of classical photographic astrometry. The new proper motions have a total 2D mean error of 0.82 arcsec/cy. Extensive quality-assurance double-checking has been performed at each stage of this work.
