  \tablefoot{Same as \tabref{Tab:n2d-weak-models}, but instead of the
    amplification factors we give the disruption time of the KH
    vortex, $t_{\rm dis}$, and the absolute value of the
    deceleration rate, $\sigma_{{\rm dec};3} = |\sigma_{\rm dec}
    / 10^{-3}|$, for simulations with $m = 256, \ldots, 4096$ zones
    per dimension.  We indicate simulations where no disruption is
    observed by a hyphen in the column for $t_{\rm dis}$,
    simulations where the determination of $\sigma_{\rm dec}$ is
    very inaccurate by a $\sim$ sign preceding the value of
    $\sigma_{{\rm dec}; 3}$, and simulations where we found no
    measurable deceleration by a hyphen in the column for
    $\sigma_{{\rm dec}; 3}$. }
