\tablefoot {Columns~2, 4, and 6 are densities averaged over boxes of Fig.~\ref{fe13dens}, and over time outside of enhanced density (``spike'') times. Columns~3,~5, and~7 are densities averaged over boxes of Fig.~\ref{fe13dens} during times of enhanced-density spikes.\\
\tablefoottext{*}{``No''~means no spike apparent within the scatter of the data.}}
