Tracker Recon Software Meeting
July 14, 2004

(Present: Bill, Leon, Tracy)
 

• Towards a new Fit Track Class
  • A start of an overview of the structure and contents of a new fit track TDS class is located here
  • Some of the resulting discussion:
    • Output of pattern recognition will be the fit track class - no pattern rec only class
    • Criteria for keeping a variable in the output class:
      • How many places in the code is it used (eg display, vertexing, analysisntuple...)
      • Alternative is to create helper classes which calculate important but infrequently used quantities
    • Class should be organized to provide forward and backward iterators over the plane hits
      • Want to remove explicit loops over plane numbers in code to allow for upward/downward track fits
         
• Vertexing/Track Topology
  • Need to begin to look at what has been called vertexing in TkrRecon
  • Will probably abandon Kalman Filter vertexing? Not applicable to our problem?
  • Bill would like to go to event topology versus "vertexing" in the  HEP tracking sense
     
• A plan for the rest of the summer's meetings:
  • No meeting July 22, both Bill and Tracy will be out of town
  • July 29: Finalize the TDS classes for clusters and fit tracks
  • August 5: Make existing code work with these new classes
  • August 12&19: Tracy unavailable for the first, Bill for both
  • August 26: First go round on a revamped TkrRecon Gaudi architecture
  • September: Begin the update of the TkrRecon code - Goal: 9/19 push the button
     
• Action items
  • Remaining from previous meeting:
    • Leon and Bill to make a list of how clusters are accessed in current code, and what other access modes would be desirable.
    • Leon to continue looking at how to improve TkrCluster and access.
  • From this meeting:
    • Bill will send us a list of critical items to be done before the next round of work on background rejection
    • Bill will start thinking about "vertexing" or an event topology stage after track fitting
    • Tracy to complete the new fit track class overview
