The coordinates of the clusters/groups correspond to the positions of the brightest cluster/group galaxies. The redshifts~($z$) and line-of-sight cluster/group velocity dispersions~($\sigma$) are taken from \citet{hal04} and \citet{mil08}. The virial radius~($R_{\rm 200}$) has been determined using Eq.~(8) from \citet{fin05}. $N_{\rm tot}^C$~gives the total number of {\it disk} galaxies (i.e.~S0$-$Sm/Im) in the cluster and $N_{\rm tot}^F$ gives the number of {\it disk} galaxies in the corresponding field. For the structures~cl1227.9-1138 and cl1227.9-1138a no S\'ersic fits could be performed, because the data only became available much later and could not be included in the general analysis anymore. \par \end{table}
