- Not all samples follow the same convention for writing the QCD scale weights into the genInfo object. - Right now we have hard coded a single type of indexing in `MCScaleVariation` that works for most samples but not all (e.g. DYJets). - A general solution has to be found to make sure each sample is treated in the appropriate way.
