Notes. Xµ and Yµ are proper motions given by Eqs. (C.1) and (C.2). ΔXµ (ΔYµ) denotes uncertainty of the corresponding quantity. The unit of all listed quantities is mas yr−1. “Comp.” denotes component of the β Lyr visual system. Column “Source”: 1. The HIPPARCOS and Tycho Catalogs (Perryman & ESA 1997), 2.
