Description:
    This table presents relative proper motions and positions for 166
    Luyten Catalogue stars re-discovered as a result of search for high
    proper motion stars in the southern hemisphere, being carried out with
    the Maksutov Astrograph at the Estacion astronomica de Cerro el Roble
    (Chile).
