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 <math>y\prime=g(x)=f(x)-(f(x+\Delta x)+f(x－\Delta x))/2=\frac{1}{2}(f(x)-f(x-\Delta x))-\frac{1}{2}(f(x+\Delta x)-f(x)) </math>
