Notes.  $\tilde\lambda$, $\epsilon_{\rm f}$, and $k_{\rm f}^{(\omega)}$ are given for the kinematic stage whereas all the other numbers are given for the saturated state of the dynamo. The last column specifies the vertical boundary condition for the magnetic field. In all runs, ${\rm Co}\approx0.8$, ${\rm Sh}\approx-0.4$, ${\rm Re}\approx12$, and ${\rm Pr}\approx0.7$. The adiabatic sound speed squared varies in the range $c_{\rm s}^2/(gd)=0.33{-}1.38$ in the domain. Six of the runs are discussed in particular detail, so we have marked them here in boldface and have also highlighted the corresponding values of ${\rm Rm}$.
