WDS 02057-2423 WSI 71 Aa,Ab : NOTES

discov_num	notes	refcode
I 454	CPD-24@891. C is CPD-24@889. AB,C = LDS 68.
	AB,C: SHY 135. Bayesian analysis by Shaya & Olling (2011) indicates	Shy2011
	very high (near 100%) probability pair is physical.
WSI 7	Aa,Ab: Tokovinin et al. (2014) derive a combined spectroscopic/
	interferometric orbit of the Aa,Ab pair, as well as a new orbit of the
	AB pair. Resulting component masses for Aa, Ab, B, and C are 0.74,
	0.72, 0.57, and 0.78 Msun, respectively.	Tok2014b
