      - fixed a bug which caused the spectra to be normalized at 1GeV
        by default instead of the integral
+     - allow the MC slope to be -1. With the current code this should
+       not be a problem anymore.

      was not using the integral anymore but a normalization energy of
      1GeV. It is now the integral again.
+
+   - sponde: Fixed a problem in the weighting which did not allow
+     a MC slope of -1.
