Abstract

A comparison of the Astrographical Catalog of Reference Stars (ACRS) and the Positions and Proper Motions Catalog (PPM) with the FK5 in the southern hemisphere, is presented. To this aim, the positions of FK5 stars uniformly spread over the celestial sphere were astrographically taken. These positions were reduced in the ACRS and PPM systems and then compared with those from the FK5 for the epoch of observation. The (FK5 - ACRS) and (FK5 - PPM) systematic differences thus obtained, in the declination range from -30o down to the South Pole, for the mean epoch of 1994.50, are shown.
