\caption{\label{t:mf}The intrinsic magnetic field strength of total $B_{\rm{tot}}$ and regular~$B_{\rm{reg}}$ 
components as well as the field regularity in different regions of NGC~4254, 
denoted in Fig.~\ref{f:magmaps} (top-right). The given uncertainties express random noise 
in the maps used. The errors, including possible systematic uncertainties due 
to applied assumptions, can reach 25\% of the values obtained. The presented 
magnetic fields strengths are taken directly from magnetic maps described 
in Sect.~\ref{s:magmaps}.
