Table 5.

Weighted mean proper motions of β Lyr A and β Lyr B.

Component	Unit	β Lyr A	β Lyr B
µ	(mas yr⁻¹)	4.03 ± 0.15	4.74 ± 0.25
θ	(deg)	157.3 ± 1.7	122.1 ± 2.9

Notes. denotes the magnitude of the proper motion vector, and θ = arctan(X_µ/Y_µ) the position angle with respect to north, where X_µ and Y_µ are given by Eqs. (C.1) and (C.2).
