Daemen et al derive component properties (units K,Lsun,Myr,Msun,Rsun):
A: SpT = M2.5 +- 0.5 Teff = 3490 +- 70 L = 0.25 +- 0.05
Age = 2.7 +0.7/-0.5 M = 0.36 +- 0.05 R = 1.37 +- 0.03
B: SpT = M2 +- 0.5 Teff = 3560 +- 70 L = 0.20 +- 0.04
Age = 4.0 +1.3/-1.0 M = 0.38 +- 0.05 R = 1.17 +- 0.02
C: SpT = M2.5 +- 0.5 Teff = 3490 +- 70 L = 0.14 +- 0.03
Age = 4.7 +2.3/-1.2 M = 0.34 +- 0.05 R = 1.04 +- 0.02
The B component is an SB1.
