-// Macro (upgraded version of MUONmassPlot_ESD.C) 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,
-// 3) Some QA histograms
-// Ntuple are stored in the file MUONefficiency.root and ESD tree and QA histograms in AliESDs.root
-
-// Arguments:
-// FirstEvent (default 0)
-// LastEvent (default 0)
-// ResType (default 553)
-// 553 for Upsilon, anything else for J/Psi
-// Chi2Cut (default 100)
-// to keep only tracks with chi2 per d.o.f. < Chi2Cut
-// PtCutMin (default 1)
-// to keep only tracks with transverse momentum > PtCutMin
-// PtCutMax (default 10000)
-// to keep only tracks with transverse momentum < PtCutMax
-// massMin (default 9.17 for Upsilon)
-// & massMax (default 9.77 for Upsilon)
-// to calculate the reconstruction efficiency for resonances with invariant mass
-// massMin < mass < massMax.
-
-// Add parameters and histograms for analysis
