Figure B.1: Components of WTTS systems placed into NIR color-magnitude diagrams together with the PMS model by D'Antona & Mazzitelli (1998). The dashed lines denote evolutionary tracks for masses from 0.02 to 0.9 M(sun), the solid lines are isochrones for ages 7 x 104, 105, 2 x 105, 3 x 105, 5 x 105, 7 x 105, 106, 2 x 106, 3 x 106, 5 x 106, 7 x 106, 107, 2 x 107, 3 x 107, 5 x 107, 108 yr (MS).

Figure C.1: Components of T Tauri binary systems placed into the HRD as described in Sect. 5. The cross gives the position of the primary, the horizontal dashed lines give the locus for the companion and the respective error. The PMS model from Baraffe et al. (1998) is also indicated. Evolutionary tracks are plotted for masses of 0.04, 0.06, 0.08 (bold), 0.10, 0.15, 0.20, 0.30, 0.40, 0.50, 0.60, 0.70, 0.80, 1.0 and 1.2 M(sun), the isochrones denote ages of 1, 2, 5, 10, 20, 50 and 90 Myr.
