  \tablefoot{The table entries are the same data as
    Table~\ref{Tab:n2d-grow-models} with the following exceptions: the
    column $\vec b_0$ is skipped, and we do not list a theoretical value
    of the growth rate. Instead, we give our choice of boundary conditions
    in the transverse direction in column ``BC''.  In the last column, we
    indicate models for which the instability grows oscillatory by a
    confirmation mark, $\surd$.  Note that model grw-3 of
    \tabref{Tab:n2d-grow-models} corresponds to model HD2r-0 with open
    boundaries.}
