cross-section normal mode

Hi

If you set the luminosity to 1e-3 in normal mode or divide any value given in main.pdf by the lumi you will get the xsec value.

New question #699323 on MadAnalysis 5:
https://answers.launchpad.net/madanalysis5/+question/699323

Dear Madanalysis team,

How can we check the cross-section of the signal or background, after applying cuts in the normal mode? I only found information about the number of events, the sum of weights in "myregion.saf". I couldn't find the value of the passing cross section.
The output pdf doesn't show the cross-section after applying cuts

Many thanks for any suggestions.

Best

FAQ #3314: “How can I create a differential cross-section plot?”.

Dear Jack,

Thanks a lot!. I have one question, The luminosity is set to 1e-3 * *10*.
Does 10 stand for Xmax/nbins? This coefficient can vary depending on the
bin size?
Please correct me if I'm wrong.
Many thanks

Best regards
