06/10/2008

• Zach: Final stages of producing initial flight calibrations including crosstalk corrections, etc.
• Fred: Working on L&EO timeline for calibration. Redoing ion rate plots layer by layer
• Berrie: Berrie, David, Zach, Sasha working on adapting David's LAC calibration model for NomSciOps data - about done. Next is FLE
• Elliott: Yvonne needs to redo energy deposit study vs angle, energy with new MC (including LPM, etc)

06/17/2008

• Berrie points out that being able to "join" AFEE temps and other calibration information would be desirable. He will look into this @ SLAC
• Fred will submit sims to Zach's requirement to SLAC or Lyon pipeline
• Fred asks who is responsible for validating filter performance during L&EO? Fred will send a note to Richard Hughes and Eric Grove about this
