\caption{Computational setup for the 2D AMR calculation T310a.
         (see Sect.~\ref{sect:AMR_2D}). The initial and final times
         over which the inner and outer grid boundaries were held 
         fixed at~$r_{\rm in}$ and~$r_{\rm out}$,
         are denoted by~$t_{\rm i}$ and~$t_{\rm f}$, respectively. $\Delta r$ is the (absolute) resolution and~$N^{\rm eff}_{\rm r}$ the number of equidistant radial zones
         that would have been required to cover the entire star
         in order to achieve a resolution of~$\Delta r$.
         Exponents are given in brackets.\label{tab:2D_refinement}}
