discov_num notes refcode
A 751 Theta and rho for 1979.7699 were incorrectly given as 178.6 degrees
and 0".106, respectively, by McAlister & Hendry (1982). McA1982d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.91 +/- 0.58, 3.41, and 2.69 Msun, respectively. Mlk2012
