Dear Francesco,



I send you the source file.

Side note: It should be d2Phi/dOmega/dE



Best regards



Klaus

Dear Klaus,



my first guess would be indeed related to the group structure. The actual group assignment resulting from the energy sampling in your source.f may be responsible for the dips. This would mean that the sampled energy value falls in the wrong group range. -

Considering that your original spectrum already follows the group structure, this hypothesis looks surprising, but a final word cannot be said without looking into your source.f.



On a side note, I understand that with dPhi you actually mean dE.



Kind regards



Francesco
