interacting/non interacting ratio (rev.)

I tried to add the subtraction histo:



It's not perfectly smooth, but it looks somewhat better in the rebinned version (see below -- in this plot the bin width is the same for all the histograms). Probably we need some simulation to understand better these bumps.




In the previous plots the normalization (done with the scaling on the maximum bin) is not correct, i.e. it leads to negative values in the blue histogram. The following one is one with HB-only correctly normalized. Now the normalization is done by comparing the area of the tail on the right side of the max (starting 2sigma far away from the peak).
