FIN 344 Spectroscopic binary.
1989.9438: This is the first observation of this system since those of
Finsen in the 1960's, and is considerably closer than any of his
results. It is known that in some instances Finsen's rho values
appeared systematically larger than those of speckle; further
observations of this system will determine whether such is again the
case. Hrt1993
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 4.24 +/- 0.59, 4.58, and 4.88 Msun, respectively. Mlk2012
