Tried fitting with different event rates, doesn't seem to help, problem might be in normalization. Created different normalization for MC spectra NormalizePDFPair
Changed normalization of M2 PDFs, needs testing
Added histogram of distribution of residuals
Implemented double gaussian smearing in SmearMC, needs testing
Added test function to try out new smearing, added SmearMCOld to keep 1 gaussian smearing for now
Tested smearing, looks good. Need to adjust code to re-add smearing histograms
Finished editing in code for 2 gaussian smearing, fit needs to be tested
Changed to 2 keV binning, fit in 2000-2650 looks really good for now...
Added loading pre-smeared histograms option, needs to be tested
Fixed error in loading file, works properly now
Fit converged, creating new MC data files with updated MC produced with latest g2root
Code current in working condition
