rawhMee.root: raw histograms filled from ntuple output of single mesons & ccbar simulations includes passCuts and branching ratio weight for ccbar, also for pt-differentialcocktail.root: final scaled cocktails/contributions as compared to data*_input.roots contain functions (and acc. histograms) for the different input sources (implementation see https://cgit.the-huck.com/cgit.cgi/BesCocktail/tree/Functions.cxx):- fM: BreitWigner to sample invariant mass for two-body decays
- fRes: MomentumResolution (MomRes) used in momentum smearing
- fCB: double-sided CrystalBall used in momentum smearing
- fKW: Kroll-Wada to sample invariant mass in dalitz decays
- fPt: Tsallis-Blast-Wave dN/dpT such that Integral{dN/dpT dpT} = 1 (Probability Distribution), resulting e+e- yield later scaled acc. to dN/dy in db.yml
