Why we need to associate tracks to clusters ?

Association of tracks to cluster is needed to know the following

Photon Conversion Efficiency ,

Clustering Efficiency,

Difference in incident track and it's cluster position ,

Understanding Photon and Charged particle clusters

and

Photon counting efficiency and Purity of the photon sample detected,
