I 454 CPD-24@891. C is CPD-24@889. AB,C = LDS 68.
AB,C: SHY 135. Bayesian analysis by Shaya & Olling (2011) indicates Shy2011
very high (near 100%) probability pair is physical.
WSI 7 Aa,Ab: Tokovinin et al. (2014) derive a combined spectroscopic/
interferometric orbit of the Aa,Ab pair, as well as a new orbit of the
AB pair. Resulting component masses for Aa, Ab, B, and C are 0.74,
0.72, 0.57, and 0.78 Msun, respectively. Tok2014b
