   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
