THE PROCEDURE

2) LOOP (int hit2) on all the hits a) consider only the ones in region iregion

2) LOOP (int hit3) on all the hits IN THE CLUSTER a) IF the hit2 you are considering in the region IS the one in the cluster (hit3), continue. ELSE try to associate it to one of the hits in the cluster (IsSttAssociate) b) if IsSttAssociate is true, add the hit2 to the cluster too.
