BU 648 Identification of the ascending node is somewhat uncertain. Stk1939
AB: Primary is SB1 and exoplanet host, P=1016d, in a 61y binary Mut2010e
(Muterspaugh et al. 2010). Wobble 1016d, 0.24mas - planet? Astrometric
orbit gives mass 1.5 Mjup if planet around B, 3 Mjup if around A. Tok2014d
AB,C: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
AB,C: Rectilinear solution by Hurowitz et al. (2014). USN2014b
