2// //
3// //
4// Basic checks for tracking and detector performance //
5//
6// For the moment (15.10.2009) the following checks are implemented //
7// - Number of clusters/track
8// - Number of clusters/tracklet
9// - Number of tracklets/track from different sources (Barrel, StandAlone)
10// - Number of findable tracklets
11// - Number of tracks per event and TRD sector
12// - <PH>
13// - Chi2 distribution for tracks
14// - Charge distribution per cluster and tracklet
15// - Number of events and tracks per trigger source
16// - Trigger purity
17// - Track and Tracklet propagation status
18//
