S 749 AB: B is BD-02@5282.
AB: HJL 280. HJL1986
AB: SHY 331. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
This cannot be the close 160.8-d spectroscopic binary. Grf2014b
AB: A is SB2, P=160.83d (Halbwachs et al. 2012) HJL2012b
AC: H 5 35. MEv2010
