Model A: $\chi=10^4$, $g/d$ = 100; B: $\chi=10^2$, $g/d$ = 10; C: Kurucz A3, $g/d$ = 10; Thick: flux for optically thick lines.
Predictions are for an assumed local line width of 0.2 km~s$^{-1}$. 
Model J is from \citet{Jonkheid_etal2007}, their model B4. 
All the line fluxes are scaled for a source distance of 140~pc.
$\Sigma_{100}$ and $p$ are the results of the power-law fitting of the modeled \CI\ surface densities (Fig. \ref{fig:coldens}).}
