MCA 74 94 Aqr. A is a long-period spectroscopic binary now resolved by
speckle interferometry.
Soderhjelm give triple solution with B (HIP 115125) instead of poor Sod1999
Hipparcos solution. The primary is overmassive, probably sp. bin.,
cf. analysis of the spectroscopic/interferometric orbit by McAlister
& Hendry (1982) McA1982c
Analysis of this observation by the techniques in use in 1985 was
unable to yield a useable result. Hrt1992b
1977.6350: This epoch was incorrectly given as 1977.6359. McA1982b
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.55 +/- 0.87, 1.98, and 1.20 Msun, respectively. Mlk2012
