\caption{\label{table-params}The parameters of the single-annulus models used in the comparison.
The first column is the identification used in this paper. 
Columns~2--4 are the stellar parameters (in units of~$M_{\odot}$, $R_{\odot}$
and~K) and Cols.~5--6 are the annulus parameters. The radius is in~AU.
All model annuli have a width $\Delta R/R=0.01$ and a grazing incident angle
of stellar radiation of $\alpha=0.05$.}
