\caption{Alfv\'en Mach numbers $M_{\rm A}=v_r/A_r$ at the locations of HD~46375~b and $\upsilon$~And~b for parallel and antiparallel directions of stellar rotation and planetary movement. The values were derived for different magnetic field strengths~$B_0$ at the
coronal base as well as different stellar rotation periods~$P_{\rm{rot}}$ and
coronal temperatures~$T$ as given in the table.}\label{tab:MA}
