Minor updates on ew corrections
Two minor updates
- The horace and winhac corrections are updated by shifting the bin edges of the post fsr mW value by -30MeV according to wrong W mass values in those samples with versions < v5; The difference was checked and found to be negligible (third digit)
- The binning in mass for the corrections have been updated where each 4 bins are merged into 1 since to have less statistical fluctuations in the corrections, this slightly reduces the constraints in the fit and slightly increases the uncertainty, indicating that the binning was indeed too aggressive.
