WDS 15200-4423 BUG 12 : NOTES

discov_num	notes	refcode
BUG 12	Burgasser et al. used two epochs of 2MASS data, as well as data from	Bug2007
	SERC, ESO, AAO plates to derive proper motion, etc. Component J,H,Ks
	magnitudes are calculated from composite 2MASS photometry, plus images
	obtained at the IRTF. Spectral types are estimated at L1.4 and L4.5,
	distance at 19 +/- 2 pc, and total mass 0.14-0.14 Msun.
