 \caption{\label{models_dc}Best fit model parameters for $\delta$~Cep and
      its CSE. $\theta_\star$ is the stellar angular diameter (mas),
      $\alpha$ the CLD~coefficient, $\theta_{\rm s}$ the shell angular
      diameter (mas), $w$ the shell width (mas) and $F_{\rm s}/F_\star$ the
      relative brightness (Fig.~\ref{model_ring}). Last column
      tabulates the reduced $\chi^2$. Only parameters with error bars
      (lower scripts) have been fitted. Note that in the second line,
      $\theta_{\rm s}/\theta_\star$, $\alpha$, $w$ and $F_{\rm s}/F_\star$, are
      set to the values found for Polaris (see Table~\ref{models}).}
