BU 395 Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
HIP 2941. See Allen et al. (2000) for information on metallicity, AlC2000
age, galactic orbital parameters, etc.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.79 +/- 0.29, 1.92, and 0.91 Msun, respectively. Mlk2012
YSC 170.
