MLR 224 Combined spectroscopic/interferometric orbit by Balega et al. (2007), Bag2007
yielding a distance of 32.23 +/- 0.52 pc, or an orbital parallax of
31.0 +/- 0.5 mas. Derived masses are 0.831 +/- 0.020 and 0.763 +/-
0.019 Msun, luminosities 0.40 +/- 0.02 and 0.26 +/- 0.02 Lsun, and
spectral types K1V and K3V.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.24 +/- 0.07, 1.60, and 0.85 Msun, respectively. Mlk2012
Mass = 0.8216 +/- 0.0037, 0.7491 +/- 0.0022 \msun for A and B. HJL2020
orbital parallax = 31.26 +/- 0.11 mas.
