Plotting code: Must be able to add systematics on top of statistical error
Effects of fiducial on subtracted particles. Acceptance should compensate for signal particle fiducial effects. Changing 3 degrees each side (L and R). Must re-calculate with +shift and -shift. Need to understand where to modify the sub-routine in the code. Add a configurable parameter (angle shift) and pass it as an option to the fiducial routine in Substraction only. Must be able to turn off and on the cut on the app, and change sign. In configuration we only have the absolute value. Add files in automatic script calculation.
What we need:
Can add shift here: https://github.com/e4nu/e4nuanalysiscode/blob/bddb3402c61d30c71b25982a4a8b9e1b4bfed20d/src/analysis/BackgroundI.h#L39
Sector to sector : we already have the plots we only need to take the difference between the sectors. Take maximum difference as uncertainty?
change beta cut in GetCharge app.
Model uncertainty on acceptance correction. Modelling FSI won't change much. We can change overall RES vs DIS scaling. Reweight?
