Pes simulation

• Correct simulation for
• Energy scale
• Energy resolution
• Shower shape
• Cross talk

3
Adjust Shower Profile

• Redistribute energies inside cluster
• 9 strips in one cluster

Changes

• Take cross talk into account.
• Changes for Shower shape implemented mainly in
  ShowerMax/PlugStripMaker
• TalkTos implemented to change parameters on the
  fly.

5
Data sample

• Easy Wenu selection (no track selection). Higher
  statistics but also contamination of background.
• Use bpel0d data sample
• Used 5.3.3 for generating Wenu MCs.
