MIP event without PE smearing?

• Why it shows spike? (not zero values)

Common common block mistake

• I though the spike might be a bug in the code
• In stead, I found the other bug
• I used own common block to copy rawhit into
  buffer.
• I thought 500 maxhit would be enough but tracker
  used higher limit (3500)
• If rawhit is more than 500 (2-3 event), it
  overwrite other ntuple block.

Ntuples

• NT block
• RawHit geant true hit
• CalObj Probably PE smeared hit
• DigHit I dont understand this. Energy entry
  holds integer.
• In old study, I used CalObj block and
  occasionally RawHit block for consistency check.
• Current code used RawHit to calculate energy. I
  dont remember why I used RawHit.
• Probably the format is slightly easier to use and
  I thought PE smearing is not big effect.

• Try to some event selection
• Low energy criteria works.

7
Leakage?

• Probably we can do very much about higher energy
  proton (KEgt300MeV)

8
Require no proton hit in last layers

• Requiring no proton hit in last some DS-Ecal
  layer
• It helps a little bit.
