Items for followup from previous meeting

1. Testing of new cal modules to measure light output and determine the range of phoelectrons expected.
2. Sensitivity to Hadronic radiation: Stepan to provide information on damage to SiPMs during NH3 pol target run. (Stepan)
3. Detailed task list of everything that needs to be accomplished to flush out the use of SiPMs. (Elton, Fernando, Carl, Eugene...)
4. Input/Decisions needed to finalize Bcal readout requirements
   • Specify the normalization and dynamic range for the number of photons/GeV in showers
   • Decide on specific grouping for SiPM sums
   • Possibility of using air gap for SiPM coupling
   • Finalize shapes of "Winston guides"
