\caption{\label{filltab}Filling factors of the chromospheres for the modelled stars and the
parameters used to calculate the filling factors. The measured scaling factor $f_{\rm m}$ between
model and flux calibrated spectrum is given as well as the theoretical scaling factor
$f_{\rm th}= R^{2}/d^{2}$.}
