CleanCluster class. Correct cluster energy by searching for constituent calo hits with anomalously high energy. Corrections are made by examining the energy in adjacent layers of the cluster
Data stored in each KDTree node. The dim1/dim2 fields are usually the duplication of some PFRecHit values (eta/phi or x/y). But in some situations, phi field is shifted by +-2.Pi
Box structure used to define 2D field. It's used in KDTree building step to divide the detector space (ECAL, HCAL...) and in searching step to create a bounding box around the demanded point (Track collision point, PS projection...)
