Let's say, in general You would find the definition of Signal & Background (as it is in BAD 1383) in fittest.C ~azzolini/Semilep01/fitter-24/VirVubFitter/fittest/fittest.C that is essencially if(truemodeB==modeB) signal; if(truemodeB!=modeB) bkg; while in case you were asking about PDF definition, (again bad 1383) you can find them in ~azzolini/Semilep01/fitter-24/VirVubFitter/fittest/ files: ccb.cxx gauz.cxx thosig.cxx but then you need to see parameters_DATA.txt parameters_MC.txt for read which parameters we give to the fit. Did you do this on R14 or higher? all the tests done until now have been done on R14. > Maybe we should repeat this on signal MC comparing R14 with a higher rel, > that should show us how much this depends on the neutrals truth matching > bug (which has been fixed in R18 and R20 just for signal MC). this is on our plans, we will let you know > > I already told Roberto, you can find the R20 skimmed signal MC ntuples > here in case these are useful for your tests: > /nfs/farm/babar/AWG23/ISL/kerstin/TrkFixup_signal/kerstin/rootples/ > (with VRU in 20.2.0d and ChargedTracks+V0BtaTrack for the charged > particles on the signal side, skimmed with TrkFixup). great thanks!...sorry for the late reply but i was doing some Gamma-Dalitz stuffs ciao ciao Virginia > Cheers, > Kerstin > >
