I’m quite new to root, I hope my question is not really obvious. Let’s say I have two histograms, h1 and h2. I get their error using Sumw2().
But how should I handle error propagation and how should I do the following operations?:
- Dividing them by a constant N, h1/N and h2/N.
- Dividing each entry by its bin width, because I have variable bin width.
- Doing the ratio h1/h2 (this one is the one I know how to do, I have seen that I should do h1->Divide(h2).
Thank you very much for your help.
