Detailed Description

Info class for PCA tracking.

This class contains the parameters of the reference frame defined by the CALO hits (either all or a subset defining a cluster). The reference frame is centered in the center-of-gravity (cog) of the hits and has the eigenvectors of the hits distribution as the coordinate axis. A threshold might have been applied in computing these quantities, and is stored as well as the eigenvalues.
