LDS 782 AB: NLTT 53397/53398 Chm2004
This system counts as single in our statistics, even though it appears
to be a triple system in reality. The reason for this is that the A
component was the AstraLux target, and the BC pair at ~7.8" is outside
of the completeness cut-off at 6". Since the BC pair is visible in the
AstraLux images, we can nonetheless analyze it astrometrically. This
pair was first reported by Beuzit et al. (2004) with rho = 0.978" and
theta = 305.8deg. There are no error bars quoted, but if we assume
that the quoted precision in decimal places corresponds to measurement
precision, and adopt errors of 5 mas and 0.5deg, which should be
conservative in that circumstance, we find that common proper motion
can be confirmed at a 76 sigma confidence level. Hence, physical
companionship can be confidently inferred, even if the errors should
be substantially larger than what we have assumed. Jnn2012
