fit missing mass of proton with linear background from g12 data. ~1.5M events

Question: Suppose there is an original function (e.g. Gaussian), what is the form of the function after bin-by-bin side-band subtraction

Answer: Suppose the function is y=f(x). The side-band subtraction makes a new function:

10M events of Gaussian distribution were generated for a histograms:

side-band subtracted and plot together with the function "-0.2*0.2/2*(-gaus(0)/[2]/[2]+(x-[1])*(x-[1])*gaus(0)/([2]**4))"
