Notes --
$N_{\rm g}$ is the number of~cluster members used in the test
($N_{\rm g}$ is identical to $\Nmemzero$ in Table~\ref{tab:zcl_sigmacl_Nmem}),
$\Delta$ is the Dressler-Shectman statistic, and
$P$ is the probability of there being
no substructure in the dataset; thus, a small value (e.g.\ less than 0.05)
indicates that substructure has been detected.
We note that Dressler-Shectman results for 5 additional EDisCS~clusters
are available in \citet{Halliday_etal:2004}.
