[Gate-users] Optical simulation doesn't match the reference

[Long Zhang]

Dear all,

The optical simulation doesn't match the reference given in the example. I
am using vGate and a customized installation based on geant4.9.4-p03,
gatev6.1, clep 2.1.0.1. Both yielded similar results.

In my simulation, the energy spectrum are shifted towards high end, but the
distribution looks correct. The cross talk is more or less the same as the
reference, but with a wider spreading.

In addition, my benchmarkPET looks fine.

Can somebody give some hints on the differences? Thank you very much!

Best regards,
Long
