  • solution unknown:
    • muon reconstruction failure at costheta = 0.6   => needs 4 FTE weeks =>Moritz
    • photon cluster position / angle bias  => theta "just" a calibration/correction issue,   phi unclear? => Daniel
    • photon energy calibration consistent with Pandora calibration
            => needs deep thinking on Pandora calibration strategy, Daniel will take a look once tautau benchmark is done
    • z0/d0 errors in fwd region => on a good way, fix requires time?
  • solution / procedure known:
    • tune BeamCal reconstruction → ongoing (Remi/Moritz)
    • calibrate LumiCal & LHCal ???
    • update parameters for beam spot constraint (LCFI)
  • validation!


  • DISK SPACE ! disk space (Cannot use tape back-end anymore) => estimate need: ~200 TB!
      => mc-opt3 currently is 600-700 TB !
            But: reduce to one detector model  => => 1 detector model = 350 TB
    keep only 10% of REC files (but all SIM files) => 25% less ?
                     simulate (hybrid simulation, reco only SiW Ecal + AHCal?AHCAL)
  • Save sim files of all events, but save REC files only for 10% a fraction of events
    → How to operate/select/control 10% files? # of split generator file base? Set additional meta key to save REC file.
    Need to investigate DIRAC codes how to save only DST files w/o producing REC files in production jobs.
    => implemented by Akiya
  • Required statistics : 2ab-1 for each channel?
    Estimate required disk space and CPU times for required statistics.
    → How about the large cross-section channel? (2f, 4f)
    → How about the 6f samples?
  • update production scripts
    • make sure whizard2 lcio file splitting works
    • Update for new directory structure and file name conventions.
      → Revisit file name convention : "wizard2" as "w2"?
    • simulate aa_lowpt and seeable pair background files. Update scripts to 250 GeV background files.
  • Need small whizard2 samples of various process type for development of production scripts.
  • Save tar-gzipped log files on tape directory.
  • File save location : DESY-SRM as primary and KEK-SRM as secondary, need to purchase  TAPEs at KEK.
  • BG samples situation
