discov_num notes refcode
STF3091 One component is probably variable; position angles have been
reversed repeatedly.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 3.96 +/- 2.41, 2.43, and 1.10 Msun, respectively. Mlk2012
The former AB,C and AB,D are now 15177-0430HL 9003. Dam2014
