Examination of the Hipparcos Proper Motion System from Lunar Occultation Analysis

Abstract

Lunar occultations were analyzed to detect errors in the proper motion system of the Hipparcos frame. The analysis suggests much larger errors in the rotation of the Hipparcos reference frame than those explained by the Hipparcos team, which were determined from the direct comparison between the Hipparcos and FK5 catalogs.
