Form of side-band subtraction histograms

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:

Test of the formula

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

side-band subtracted and plot together with the function:
