Help Poisson Errors.

  1. May 19, 2013 #1
    So I have a histogram with bins that contain the number of events expected at a specific energy (which I generated with a Monte Carlo).. I need to add (integrate) all the bins in a section of this histogram and find the error of this value. However, the number of events are very small approx 10^(-1) so I can't just add the error of each bin in quadrature. So how do I calculate the error on the result of my integration over a section of the bins?
