7 | // --------------------- | |
8 | // Implementation of a track to be used for EMCAL track matching. | |
9 | // This object is used to find track intersection with EMCAL surface | |
10 | // in order to find the most well matched EMCAL cluster to associate to it. | |
11 | // NO Kalman-like parameter updating is done. | |
