One of the most important problems of modern astrometry is constructing of an ideal inertial coordinate system. A bulk of up–to–date star catalogues is referenced to an equatorial frame, which is far from being really inertial, Some attempts were made to remove this defect by excluding both nutation and precession in right ascention [Guinet 1979, Murray, 1990]. This proposal seams to be a compromise between the existing tradition and the new requirements met by the modern astrometry.
