WDS 08228-5727 LDS 217 AB : NOTES

discov_num	notes	refcode
BRG 27	Aa,Ab: As noted in Bergfors et al (2010), this is a triple system with	Brg2010
	component B outside of 6". Hence, we do not include component B in
	Table 4, but we note that at 8.429+/-0.001" separation in 2008.88 and
	8.374+/-0.003" in 2010.09, there is statistically significant orbital
	motion also for this component.	Jnn2012
