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