Dear all,

this correction improved the bump splitting for pi0-events, but i still have a problem with gamma gamma events and there is still a factor of 2-5 for the background above 3 GeV to suppress.
Here a little macro to explain.

Please please run it with:
root -l "Fehlersuche.C(\"gammagamma.root\",7.5298 )"
root -l "Fehlersuche.C(\"pi0pi0.root\",7.5298 )"

Many single gamma-clusters in the shashlyk are split in two.
Maybe someone can help me?
Thank you,
Irina
