|
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. |
