  \tablefoot{The columns give the initial shear
    velocity, $U_0$, Mach number, $\Mach$, magnetic field strength,
    $b_0$, and Alfv\'en number $\Alfv$. The models were simulated on
    grids of $128^3$ to $512^3$ zones using parallel ($+$ sign) and
    anti-parallel ($\pm$ sign) initial field configurations,
    respectively.  Most of the models were simulated several times
    using different initial perturbations.  }
