None Wrong optical photon parameters interpolation

Hello all! I try to simulate scintillation counter and I have used the data files to describe different scintillator properties. For example, I used a data file with a digitized emission spectrum to set "FASTCOMPONENT" property. Result of simulation is strange... Please, see attachment. The input data shown in red and Geant4 produced spectrum is in black. Instead of linear interpolation, Geant4 makes very strange interpolation between data points. I have found similar reports in the forum but I didn’t find any solution of the problem…. Could anybody recommend anything how to solve the issue????? P.S. One more question…. If I should enter all scintillator parameters at the same energy grid? For example with step 0.1eV: 1eV, 1.1eV,1.2eV…. 10eV... etc. Or it is possible to use different energy grids for different parameters? For example “FASTCOMPONENT” is defined at energy step 0.1eV, “RINDEX” with step 1eV and “ABSLENGTH” with step 2eV….
