Detailed Description

ClusterMaking is currently defined as a process which uses Cells from the TES and forms Clusters from them.

The strategy employed is to sum all Cells in a given R-cone around an initiator.
[Note: This might be more correctly called pre-jet formation as the R-cones are of jet size and therefore this algorithm does not really correspond to the normal notion of forming clusters from,say, adjacent energy deposits.]
