discov_num notes refcode
A 2700 Masses and bolometric magnitudes are derived for the two components
of this system by Mason et al. (1999), based on assumed spectral types Msn1999a
and available parallaxes.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.82 +/- 0.51, 1.91, and 1.17 Msun, respectively. Mlk2012
