STF1865 zet Boo = 30 Boo.
Spectral types and masses of components assigned by ten Brummelaar et
al., based on adaptive optics observations. TtB2000

Errors for orbit of Alzner (2007) provided by author (private comm.) Alz2007
Hipparcos parallax yields a mass sum 7.95 Msun, rather high for a pair
of A0V stars. Increasing parallax by 1 sigma (1.24mas) yields a more
reasonable mass sum of 6.51 Msun, however.
Calculated mass sum is 122 +/- 275 Msun, unconstrained. Mut2010b
AB: Additional notes may be found in Fu et al. (1997) McA1997
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 5.60 +/- 1.66, 5.20, and 4.48 Msun, respectively. Mlk2012
