FIN 333 Probably an ambiguous case, although only one solution has been
tested.
More speckle obs needed to define orbit.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 14.55 +/- 4.04, 2.67, and 1.20 Msun, respectively. Mlk2012
