Agenda

Review action items from previous meeting

  • Send e-mail to Andrei and Irina pointing them to the BCAL smearing code where the new Poisson sampling was introduced (David)
    Completed
  • Measure inherent energy resolution of hdgeant/mcsmear chain without sampling fluctuations turned on. (David)
    See today's slides
  • Write description of how we should incorporate sampling fluctuations in the smearing code (Elton)
    ?
  • Write description of how we should incorporate sampling fluctuations in the smearing code (Andrei)
    Briefly outlined in June 10th email:
    • "About the implementation of realistic energy resolution in readout cells (because of the sampling fraction): I do believe that we can use the Fluka simulation of the BCal modules with detail structure that Irina did for 90 and 20 degree emission of photons in the range up to 2 GeV. We can compare the relative width of Fluka spectra from the cells with the relative width of the correspondent HDGEANT spectra (energy depositions in the homogeneous material only, all extra-widenings are off); the difference will give us the correction we need to introduce into the simulation as a function of cell, energy, angle etc."
  • Check and document input distributions to profile histograms to make sure tails and second peaks don't significantly affect the mean. (David)
    Not necessarily completed. Plots circulated on June 11th.
  • Follow up on status of GlueX code documentation. (David)
    Work has started on updating/enhancing documentation as reported at the June 15, 2011 offline software meeting.
