By convention, the first strip added to the cluster is considered to be the "seed" strip.

Author: Jason C. Webb Jason.nosp@m..Web.nosp@m.b@Val.nosp@m.po.e.nosp@m.du

Class which represents an SMD cluster. This class derives from StEEmcBaseCluster, which allows matching of clusters between layers by storing a unique cluster ID.

To build a cluster, one uses something like the following recipe

*
* StEEmcSmdClusterVec_t list_of_clusters;
* StEEmcSmdCluster cluster;
*
* // Get the seed strip from StEEmcA2EMaker 0=tower 1=pre1 2=pre2 3=post
* Int_t plane = 0;
* StEEmcStrip seed = mEEanalysis -> strip( sector, plane, index_of_seed_strip );
*
* cluster.add( seed );
*
* // Next, loop over all hit strips and add any which satisfy your clustering
* // criteria by using cluster.add(strip).
*
* // Finally, add the cluster to storage
* list_of_clusters.push_back(cluster);
*
* 

The energy, mean and sigma of the cluster are calculated in flight. One can override this by calling the energy(e), mean(m) and sigma(s) methods.

Strips can be added with a weight.
