Hello everyone, As requested, I have remade the plots with error bars: http://www.slac.stanford.edu/~penguin/VubRecoil/R18migERR/index.html > it would be certainly useful as suggested by Wolfgang to have also some > kind of normalized plots. Just to clarify: Most of the plots ARE normalized - the histograms are divided by the number of entries in the given chain. The only plots that are not normalized are the "number of X vs run number" plots. > I would not say that Run2 and Run3 are consistent.

A similar pattern is observed for the > number of muons in the comparison between Run2 and Run2MC but not visible > in Run3 vs Run3MC. Yes, you're right. Sorry I missed that. sheila
