HDS1895 Horch et al (2012) generate two possible orbits, one based on only Hor2012a
astrometry, the second "constrained" solution fixes P, T, e, and Omega
to values determined in a spectroscopic orbit by Torres et al. (2002). Trr2002
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.27 +/- 0.49, 1.75, and 0.88 Msun, respectively. Mlk2012
Ren & Fu (2013) calculated an astrometric orbit, combining Hipparcos
Intermediate Astrometric Data with spectroscopic elements by
Latham et al. (2002). They derived component masses 0.93 and 0.42 Msun Lat2002
and an estimated semimajor axis of 95.29 mas. Ren2013
