Fitting a rebinned spectrum results in wrong peak volume

If a peak in a spectrum is fitted that has just been rebinned by spectrum rebin X, the peak volume given by the fit is X-times higher.

Integrating is not affected.

Steps to reproduce: Load a spectrum, fit a peak. spectrum rebin 2, fit peak.

Workarounds:

  • Divide peak volume after fitting by rebinning factor
  • Write rebinned spectrum to file and load it (different calibration required)
