WDS 22234+3228 WOR 11 : NOTES

discov_num	notes	refcode
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
