WDS 02490-1029 BRG 16 BC : NOTES
 
 
discov_num notes refcode
BRG 16 The system is precisely at the 3 sigma threshold for statistically
significant exclusion of the background star hypothesis. By chance,
the AB astrometry is just below the criterion (2.7 sigma) and BC is
just above (3.1 sigma), so in principle the BC pair is inconsistent
with chance alignment, if the pair does share a common proper motion
with A. However, the proper motion of the system has of course been
determined based on A, so until the AB physical connection has been
demonstrated to the required accuracy, the 3.1 sigma confidence of the
BC pair is irrelevant. Hence, we label the entire system as
undetermined for now, although it is obviously very likely that the
whole system is indeed bound. Jnn2012
