A Comparison of the SAOC with the AGK3 Classical Analysis.
Abstract
A classical problem in astrometry has been the evaluation of the systematic differences of the positions and proper motions in different star catalogs. Such investigations are important because they can reveal both small systematic differences in data reduction, observing technique, etc., and mistakes such as digit transposition, star mis-identifications, etc. Until very recently such investigations have been severely limited in scope because of the tremendous computational load involved. Such considerations are rapidly diminishing in importance as computing power increases and the availability of machine readable catalogs improves. This Report compares two very large star catalogs; the smaller contains 183,145 stars and the larger has 258,997 entries.
