CLO 3	Assuming a parallactic distance of 26.67 +/- 2.63 pc (Costa et al.	Jao2006
	2006), Konopacky et al. (2010) derive system mass 0.16 +/- 0.05 Msun.	Kon2010
	Dupuy et al. (2009) also reprocessed the HST/WFPC2 data originally
	published by Bouy et al. (2003), as well as the Gemini/Hokupa'a data	Boy2003
	originally published by Close et al. (2002). From their orbital	Clo2002a
	solution they derive a total system mass of 0.15 +0.05/-0.03 Msun.
	Spectral types appear to be M8.0 +/- 0.5 for both components. Distance
	is estimated at 26.7 +2.6/-2.1 pc.	Dup2009b
