On the basis of Hipparcos data, whose system is believed to be quasi-inertial to within +/-0.25 mas yr-1 and to represent an internally consistent reference frame, we carried out an analysis of the SPM 2.0 proper-motion system. Comparing the Hipparcos proper motions with those of the SPM 2.0 Catalog, which provides absolute proper motio…
