Don't know uncertainty of weight after cuts in expert mode

Asked by Jakob Lundström

Hello,

I can't seem to find a way to calculate the weight error in a signal region after selection cuts.

Is there something I am missing?

Best regards,
Jakob

Is this not a question for MadAnalysis5? (if so I can assign the question to the correct team)

Cheers,

Hi Jakob

Are you trying to access the weights written in the HEPMC file in expert mode? for that you need to use mc()->multiweights() accessor which gives you a vector for all the weights written in your HEPMC file.

Cheers

I'm using lhe files and I'm wondering whether there is a way to display the uncertainty of the sum of events that is displayed in the cutflows saf file somewhere? (In the terminal after finalizing, for instance)

Hi Jakob,

This is an on-going development and should not be used at the moment, as not finalised (many functions are missing and the information is still not processed at the python level).

Cheers,

Benjamin
