Detailed Description

Create clusters of maximum size NxM.

This class derives from AliEMCALClusterizer but also keeps the API of AliEMCALClusterizerv1 Algorithm:

pick the most energetic cell
assign it as a center of the cluster and add cells surrounding it: 3x3, 5x5...
remove the cells contributing to the cluster
start from 1 for the remaining clusters
cluster splitting (not implemented yet) - use the shape analysis to resolve the energy sharing

for high energy clusters check the surrounding of the 3x3 clusters for extra energy (merge 3x3 clusters and resolve the internal energy sharing - case for 2 clusters merged) Use Case: root [0] AliEMCALClusterizerNxN * cl = new AliEMCALClusterizerNxN("galice.root") Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated //reads gAlice from header file "..." root [1] cl->ExecuteTask() //finds RecPoints in all events stored in galice.root root [2] cl->SetDigitsBranch("digits2") //sets another title for Digitis (input) branch root [3] cl->SetRecPointsBranch("recp2") //sets another title four output branches root [4] cl->SetTowerLocalMaxCut(0.03) //set clusterization parameters root [5] cl->ExecuteTask("deb all time") //once more finds RecPoints options are // deb - print number of found rec points // deb all - print number of found RecPoints and some their characteristics // time - print benchmarking results

virtual

Gives the neighbourness of two digits = 0 are not neighbour ; continue searching = 1 are neighbour = 2 is in different SM; continue searching In case it is in different SM, but same phi rack, check if neigbours at eta=0 neighbours are defined as digits having at least a common side The order of d1 and d2 is important: first (d1) should be a digit already in a cluster which is compared to a digit (d2) not yet in a cluster
