Notes

Abhyuday

• Runlist looking at when calorimeter calibration changes
  • E/p a little high after calibration (0.2-0.5% high)
  • We suspect that this is within resolution and uncertainties
• Weird wiggle in E/p at positive Delta
  • 4589 - wavy - Positrons. Possibly background related
  • 4490 - Not wavy
  • Cameron checked runs from another experiment and it seems consistent with positive polarity running

Cameron

• Looking at elastic singles
  • Has begun analysis and is getting SIMC working

All

  • Abhyuday is going to double check our discussions today with Dave
