Sampling Weights

• Determined from 10 GeV charged pions
• Minimize
• (1/N) S (E0 aiLi)2
  where
• E0 is the incident energy
• ai is the weight for layer i
• Li is the energy/number of hits in lyr i
• For simplicity i2 considered here

Comments

• The gain in going to non-projective geom is about
  what we expected (20)
• But we are not comparing the same thing
• SDMar vs SDJan
• GISMO vs G4
• EMCal sampling is different
• Need to convert these to jet resolutions
