WDS 16093-2008 BIL 6 : NOTES

discov_num	notes	refcode
BIL 6	Biller et al. (2011) derive spectral types for the two components of
	M7 +/- 0.5 and M6 +/- 1.0; Teff = 2990 +/- 60 and 2850 +/- 170K.
	Assuming an age of 5 Myr, masses are 79 +/- 17 and 55 +/- 25 Mjup. If
	the system age is 10 Myr, these increase to 84 +/- 15 and 60 +/- 25
	Mjup. Component JHK magnitudes are derived from 2MASS magnitudes,
	combined with NIRC2 magnitude differences.	Bil2011
