discov_num notes refcode
SEE 170 The RV's of 1916 are quite uncertain. There may be a variation, and
it may be related to the visual motion. The A component is also a
Beta Lyrae-type system.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
One component is V831 Cen, a beta Lyr system and also an SB with
orbital period ~0.64d. Zas2009
