a The effect of the deconvolution with an ideal and a detailed PSF is specified for the model by Steffen (Ch0). The extent of the detailed PSF corresponds to (1) only the size of the model and (2) a periodic repetition of the model to a size of 110 $\hbox{$^{\prime\prime}$ }~\times~$110 $^{\prime\prime}$, which is comparable to the FOV of the observations.
$^{{\rm b}}$ For comparison, the original, i.e., non-degraded contrast values for sets of CO5BOLD models (Ch1, Ch2, and Cm) and simulations by Stein & Nordlund (SNh and SNm) are given.
