Detailed Description

This class collects some information of a TrueHit, using SVDCLuster and MCParticle information too.

This information is: position in local and global coordinates at entry/middle/exit position of the sensor, momentum, analytical track parameters (evaluated from position and momentum), geometrical information (layer,ladder,sensor) and time.

The purpose of this class is to obtain a single "hit-like object" with all the useful information for a track-parameters study. It is used in evaluate the NoKickCuts.

To build a hitXP object is necessary to use the constructor of the derivate class hitXPDerivate.
