  \caption{Initial magnetic energy~$E_{{\rm mag}}$ and typical values of the ratio of magnetic to
  gravitational energy~$\beta_{{\rm mag}}$ (the exact values depend
  also on the hydrodynamic initial model and its gravitational energy)
  for the models of series~AaBbGg-DdM12. The magnetic energy of models
  with $b_0 \ne 10^{12}~{\rm G}$ can be obtained by a~simple
  scaling relation, e.g.~$E_{{\rm mag}}^{{\rm AaBbGg-D2M10}} =
  E_{{\rm mag}}^{{\rm AaBbGg-D2M12}}~ (10^{10} / 10^{12})^2$. }
