4 // Basic checks for tracking and detector performance //
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
13 // - Chi2 distribution for tracks
14 // - Charge distribution per cluster and tracklet
15 // - Number of events and tracks per trigger source
17 // - Track and Tracklet propagation status
