MCA 40 A spectroscopic triple system, with periods 101.6 and 3320 days.
The long-period pair has covered more than half its orbit; the orbit
may be determinable. Bag1984a
Barlow & Scarfe (1991) give combined spectroscopic/speckle Scf1991
interferometric solution.
1985.5226: This measure was found to give very large residuals to the
orbit of Barlow & Scarfe (1991). Comments in our reduction log note Scf1991
the measure was marginal, and after reinspection we have determined
this measure was spurious. Hrt1992b
Martin et al. (1998) derive component masses 3.344 +/- 1.000 and
3.289 +/- 0.988 Msun. Mig1998
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 6.55 +/- 1.65, 4.67, and 1.05 Msun, respectively. Mlk2012
