Vertex Reconstruction: muDst status

Updated on Thu, 2016-12-29 15:21. Originally created by smirnovd on 2016-12-01 14:09.


Caveats while using muDst as input for vertex finders (currently PPV):

  • There are cuts applied to Sti global tracks before saving them to muDst (different number of input tracks)
  • NHit check is essentially nHitFit/nHitPoss > 0.51 (0.7) (in PPV calculated manually)

raw daq (full reco) muDst (global tracks) 
PPV:: # of input track          = 7087
PPV:: dropped due to flag       = 0
PPV:: dropped due to pt         = 2719
PPV:: dropped due to PCT check  = 0
PPV:: dropped due to DCA check  = 3677
PPV:: dropped due to NHit check = 614
PPV:: # of track after all cuts = 77


PPV:: # of input track          = 7087
PPV:: dropped due to no cov     = 186
PPV:: dropped due to pt         = 2653
PPV:: dropped due to PCT check  = 0
PPV:: dropped due to DCA check  = 3554
PPV:: dropped due to NHit check = 623
PPV:: # of track after all cuts = 71
