I have an application where I am scaling a histogram by a factor that itself has an uncertainty associated with it. Is there a function with the TH1 class that would multiply the histogram and propagate the error on the scaling factor to the error on the bins? I’m surprised that I can’t find such a function, but it could be that I’ve missed it. I would like something like:
TH1F *h = new TH1F(/* Set up histo here */); double k = 10; double kErr = 3; h->ScaleWithErrorPropogation(k,kErr); // does something like this exist?
