18 // Macro (upgraded version of MUONmassPlot_ESD.C, better handling of Jpsi) to make :
19 // 1) Ntuple (Ktuple) containing Upsilon kinematics variables (from kinematics.root files)
20 // 2) Ntuple (ESDtuple) containing Upsilon kinematics variables from reconstruction and
21 // combinations of 2 muons with opposite charges (ESDtupleBck will be used later)
22 // 3) Some QA histograms
23 // Ntuple are stored in the file MUONefficiency.root and ESD tree and QA histograms in AliESDs.root

33 // 553 for Upsilon, 443 for J/Psi
