discov_num notes refcode
MCA 73 74 Aqr. A spectroscopic, occultation, and interferometric system. The
interferometric pair is not the spectroscopic pair, so the system is
at least triple. Msn1997a
1977.4874: Theta incorrectly given as 92.8 degrees McA1979b
First detected as an occultation binary by Blow et al. Blw1982a
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 23.11 +/- 7.09, 6.98, and 3.09 Msun, respectively. Mlk2012
