Re: Question Sciintillation Emission Spectrum table (Ron Mathis)

Hello Ron,

Can you please check what scintillation photon energies are sampled and put on the stack (by putting the histogram in StackingAction). The code for interpolation of the MaterialPropertiesVector has not changed for a very long time and is a simple linear interpolation between points:

From this intensity distribution an integral intensity distribution vector is made at:

where the integration between points is easy by assuming a linear increase. The photon energy points in that vector are the same as your input. In any event, I can't see how gaps can result from sampling this integral table at:

where the G4PhysicsOrderedFreeVector is also linear interpolated:

There was however a small change made to the G4PhysicsOrderedFreeVector on Jul 03, 2009 V.Ivanchenko (global-V09-02-06). What happens if you changed the 9.3 version of that class by the 9.2 version?
