Hi all,

I have an update to my previuos post.

The previous plots were shown for G3 simulation, but in case of G4 simulation the energy correction taken from Babar framework works better.

The barrel emc - 25-135 degree, 1 GeV gamma.

index.php?t=getfile&id=4873&private=0

At least the mean value of corrected histogramm is at 1 GeV.

And shashlyk calorimeter, 0-5 degree, 1 GeV.

index.php?t=getfile&id=4874&private=0

The match is not perfect but much closer than in G3 case.

Best regards,
Dima
