Tracking Library

• Tracking Code is available @ http://blinkin.krl.caltech.edu/progressive_tracking/tracking.tgz
• Brief Introduction to each Classes
  • THaSolenoid (inherited from THaSpectrometer)
    • Template class for Solenoid detector
  • SOLGEM (inherited from THaTrackingDetector)
    • Main class for the tracking detector.
    • Tracking is performed in the "coarsetrack" and "findtrack".
    • Additional methods are written to help the track finding.
  • THaGemHit
    • This class is to store the hit information on the GEM. It provide various methods to save/extract the hit information, e.g. x,y,z,r,phi etc.
    • This function is used to store the information from detector (NOT the true simulated information.
  • THaGemTrack
    • This class is to store the track information from the progressive tracking algorithm. One can save/extract various information related to the reconstructed track in this class. One can also sort the tracks to do the de-ghost.
    • Information can then be saved into the final output rootfiles.
  • THaShowerHit
    • This class is added to store the hit information on the calorimeter. One special variable is the sector number.
    • This class is added for PVDIS tracking after the development of SIDIS progressive tracking.
  • THaSoleSimTrack in THaSoleGEMSim.h
    • Stored the saved true simulated track information from simulation.
    • Information can be then saved into output rootfiles.
  • THaSoleSimHit in THaSoleGEMSim.h
    • Stored the saved true simulated hit information from simulation.
    • Information can be then saved into output rootfiles.
  • THaSoleSimRun (inherited from THaRunBase)
    • Template class
    • In this class, we calculate the additional false hits from the real hits (from both tracks and background hits). In principle, this part should be merged into the converter part.
  • THaSoleSimDecoder (inherited from THaEvData)
    • This is the class that one can load event information from the rootfiles.
