PROPOSAL warnings when creating (muon) tables
With the introduction of the v_cut, for specific emcut settings, PROPOSAL starts to print a bunch of warnings when creating tables, saying something like:
[CrossSection.DNDX] [warning] Negative dNdx value for E = 343.3786 MeV, vbar = 1.0000 detected in interaction type Epair. Setting dNdx to zero.
This is due to some numerical problems of the interpolation close to the emcut. However, this is for cross sections in energy regimes that are irrelevant for shower development.
We should keep this problem in mind when re-writing the table handling for the beta release. I believe that with the plans we developed at the workshop, this might be automatically fixed.
