* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly. |

* Each track may have an "image", due to the ambiguity on the Y view, which is stored also. |

* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ). |
| 149 |
* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ). |
