Detailed Description

Cluster energy variation component in the EMCal correction framework, for EMCal systematics.

This component allows the cluster energy to be scaled by a constant factor and smeared by a random value drawn from a Gaussian with specified width. Note that you must configure the input cluster container (in the YAML file) with the desired default cluster energy type (nonlincorr, hadcorr, etc) to be shifted/smeared. The shifted/smeared energy is written into the user-defined cluster energy field AliVCluster::kUserDefEnergy1, which can then be retrieved in later tasks through AliVCluster::GetUserDefEnergy() or through the usual cluster container machinery (see
