HDS1862 1988.1655: Unresolved upon initial inspection (McAlister 1993), a very McA1993
weak peak was later found which agreed well with the Hipparcos
measurement. Msn1999b
BGH 46 AB: HJL1077. HJL1986
AB: SHY 617. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
