WDS 04221-2849 BWL 15 : NOTES

discov_num	notes	refcode
BWL 15	Pair is a 0".7 equal-flux K7V2 binary. Torres et al. (2006 A&A 460,
	695) found strong Halpha emission and lithium absorption. Age is
	consistent with that of the Pleiades, so an age range of 50-200 Myr
	is adopted for this system.	Bwl2015
