Systematic relations between the HIPPARCOS catalogue and major (fundamental) catalogues of the 20th century (Paper II)

Abstract

Presented are the systematic relations between the HIPPARCOS catalogue and major catalogues of the 20th century, not yet treated in Paper I. Colour-dependent errors in the catalogues are also determined and eliminated. The derived systematic relations allow one to reduce observations given in the system of one of the analyzed catalogues to the HIPPARCOS system. The necessary software and the required input data can be downloaded from http://www.ari.uni-heidelberg.de/fk6/sysdiff. Other catalogues may be added from time to time.
