Fix rivet-mkanalysis to use LeptonFinder correctly
Sorry, very minor thing, but it caught me out and I spent an hour debugging it, so here's making sure it never happens again.
In the DressedLeptons
->LeptonFinder
change, the order of the lepton and photon projections in the constructor was swapped. But the example analysis in the rivet-mkanalysis script did change DressedLeptons
->LeptonFinder
, but didn't change the order. So the example was misleading.
