Hi Sheila, it would be certainly useful as suggested by Wolfgang to have also some kind of normalized plots. Normalized to 1 and then also calculating the ratio between different Runs or between data and MC would already tell us if the shapes of the spectra have changed. I would not say that Run2 and Run3 are consistent. There seems to be a discrepancy in the muon momentum spectrum a high momenta. This is also reflected in the number of muons. A similar pattern is observed for the number of muons in the comparison between Run2 and Run2MC but not visible in Run3 vs Run3MC. Cheers, Heiko P.S.: I'm probably late for the meeting due to a seminar I have to attend.
