WDS 00324+0657 MCA 1 Aa,Ab : NOTES

discov_num	notes	refcode
MCA 1	51 Psc. A is a triple occultation system, and a resolved
	interferometric pair. B is BD+06@65.
	First detected as an occultation binary by Africano.	Afr1976
	Mason et al. give Aa,Ab,B triple solution (double (Aa)-B in HIP).	Msn1997a
	Orbit mostly dependent on Hershey pc obs; more IR speckle needed.	Hry1973
	The Aa,Ab components of ADS 449 apparently went through periastron
	some time during 1987-1990.	Hrt1992b
	Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 3.08 +/- 0.46, 3.66, and 2.40 Msun, respectively.	Mlk2012
STF 36	AB: H 4 70.	MEv2010
