\caption{Observed targets and used model parameters. Data for the $V$-band
magnitudes are from  Herbig \& Bell (\cite{herbig88}) 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 (\cite{johns97}); $\log \dot M$ for CT Cha is from
Hartmann et~al. (\cite{hartmann98}), for RU Lup from Lamzin et~al.
(\cite{lamzin01}) and for RY Lup from Gahm et~al. (\cite{gahm93}). 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.\label{tab:stars}}
