Description
Hello
I have a question - When interfacing Delphes with a MG@LO lhe file, I see in the end that genweights are not unity - Is it something expected ? My understanding is that when using unweighted lhe events, genweights should be one. Does that make sense ?
Regards
Alexis

Ah, ok - I realized that actually what is important that each event should have the xsec/Nevents weight, so obviously it does not have to be unity, rather than it has to be the same for each of the final events.
