WDS 03182-6230 ALB 1 AB (Zet2 Ret) : NOTES

discov_num	notes	refcode
BNU 2	Aa,Ab: zet 2 Ret. B has common proper motion, +1370 +660, and is
	CPD-63@217 = zet 1 Ret.
	Aa,Ab: Likely a spurious pair. Last measured 1978 and unresolved by
	SOAR on 3 occasions 2008â€“2012.	Tok201
	Aa,Ab is suspicious, 1 observation in WDS, not binary in Raghavan et	Rag2010
	al. (2010). Jones et al. (2002) do not detect SB with precise RV at	CPS2002b
	the AAT.	Tok2014d
ALB 1	AB = LDS 92. HIP 15371. See Allen et al. (2000) for information	AlC2000
	on metallicity, age, galactic orbital parameters, etc.
	AB: SHY 16. Bayesian analysis by Shaya & Olling (2011) indicates very	Shy2011
	high (near 100%) probability pair is physical.
