WOR 11 Also known as GJ 856, this is a well studied binary with several
astrometric data points over a long baseline. In Table 4, we present
the AstraLux data as well as one example data point from literature,
and otherwise refer to Seymour et al. (2002) for more information on USN2002
the astrometric data and a preliminary orbit fit. Lopez-Santiago et al
(2006 ApJ 643, 1160) classify the system as a member of subgroup B4,
with an estimated age of ~100 Myr. Jnn2012
