Preliminary offline data analyses
Ebf library from onLine group
Ebf file
Reconstructed Root file
Gleam from software group
Muon calibration scripts from CAL group
High Level data analyses

Conclusion
  • Preliminary results shows TKR works much better
    than last time
  • Infrastructure required for data taking (In
    progress by the online group)
  • Where the ebf files are stored?
  • How to get info about each run?
  • Can we automate file transfer?
  • Objectives for data taking
  • Perform CAL only calibration using NRL offline
    scripts (Sasha Xin)
  • Perform CAL calibration using TKR with NRL
    offline scripts (Sasha Xin)
  • Study charge sharing in TKR (Jason, see his talk
    tomorrow 415)

  • 1. Use Gleam to convert ebf file to digi root
    file
  • 2. For the tracker, no calibrations are done
    offline
  • For the calorimeter, run muon calibration
    scripts to produce calibration constants xml
    files.
  • 3. Gleam reads in the digi root file and
    calibration constants, performs reconstruction,
    produces several root files.
  • 4. ROOT tree analyses
