WDS 15019-0135 ART 2 : NOTES

discov_num	notes	refcode
ART 2	Artigau et al. (2011) derive spectral types L4.5 +/- 0.5 and L5.5 +/-
	1.0. Distance for A is estimated at 31 +/- 5 or 44 +/- 7 pc, depending
	on whether it's a single object or an equal-luminosity binary.
	Distance for B is estimated at 56 +/- 8 pc. Total mass <0.12 Msun if
	double, <0.18 Msun if triple.	Art2011
