Questions/Answers
Which dataset are you using (2015 and/or 2016)? Which reprocessing or prompt reco?
ANSWER
2016 Rereco
If the definitions of the muon ID and Isolation variables you are using do not correspond to the official working point, could you explain us why?
ANSWER
It is official one.
Are the efficiencies taken from central numbers or recomputed individually for the analysis? (reply for ID, Iso, Trigger)
ANSWER
Yes all scale factors are taken from central numbers for ID,Iso and Trigger
If the efficiencies are recomputed, are there plots showing level of agreement with central results? (reply for ID, Iso, Trigger)
ANSWER
In case of disagreements, are those justified by differences in selection/particularities of the analysis? (reply for ID, Iso, Trigger)
ANSWER
How are the efficiency numbers used? Are they applied as scale factors to MC? In bins of eta/pt? (reply for ID, Iso, Trigger)
ANSWER
Yes they applied as scale factors depending the eta and pt of muon for ID, Iso and Trigger.
Which are the errors assigned to efficiencies? How do they exactly propagate into the analysis? Are there systematic uncertainties computed and propagated into the analysis that account for differences between Zs and analysis phase space? (reply for ID, Iso, Trigger)
recommended Central errors depending on the eta and pt of muon varied up and down and the difference took as uncertainty separately for ID, Iso and Trigger
ANSWER
In case no efficiency corrections are applied, is there any systematic error taken into account in the analysis for this? (reply for ID, Iso, Trigger)
ANSWER
How is the momentum scale and resolution taken into account?
ANSWER
They are very small in this analysis and not considered.
