Detailed Description

Reduced EMCAL cluster information.

This object stores a reduced set of information of a reconstructed EMCAL cluster

• unique ID of a cluster in the event (for cluster-track matching)
• energy of the cluster
• position of the cluster in ( \( \eta \), \( \phi \))
• shower shape parameters This object is part of the reduced event structure for the high- \( p_{t} \) analysis
