Table 1: Observed targets and used model parameters. Data for the V-band magnitudes are from Herbig & Bell (1988) and the SIMBAD database. Data for $v \sin i$ and $v_{\rm rad}$ and $\log \dot M$ for Sz 68 are from Johns-Krull & Hatzes (1997); $\log \dot M$ for CT Cha is from Hartmann et al. (1989), for RU Lup from Lamzin et al. (2001) and for RY Lup from Gahm et al. (1993). No accretion rates were found in the literature for CV Cha. All other parameters (except for the Sun) are results of this paper. In addition to the tabulated values we used $[{\rm Fe} / {\rm H}] = 0.0$ for synthetic spectra calculations.
