A 1874 AB: Kiselev et al. derive a family of possible orbital solutions, Rmn2009
based on a range of mass sums (0.93 to 1.53 Msun) and inclinations of
the pair to the plane of the sky (-32 to +32deg).
STFA 32 AC: HJL 242. HJL1986
AC: Kiselev et al. derive a family of possible orbital solutions, Rmn2009
based on a range of inclinations of the pair to the plane of the sky
(-38 to +38deg). The mass of the AB pair is here assumed to be 1.09
Msun and that of the system 1.89 Msun.
AC: SHY 84. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
