- pyhf.readxml.extract_error(hist: uproot.behaviors.TH1.TH1) list[float] [source]
Determine the bin uncertainties for a histogram.
If fSumw2 is not filled, then the histogram must have been filled with no weights and .Sumw2() was never called. The bin uncertainties are then Poisson, and so the sqrt(entries).
uproot.behaviors.TH1.TH1) – The histogram
The uncertainty for each bin in the histogram
