\tablefoot{The columns give the initial Mach number, $\Mach$, the shear-layer width, $a$, the initial magnetic field strength, $b_0^x$, the corresponding
\Alfven~number, $\Alfv$, and the amplification factors $f^{\rm e}$ (for
the magnetic energy) and $f^b$ (for the field strength), respectively.  The models were simulated on grids of $m = 256, \ldots, 4096$ zones per dimension.}
