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
