+// 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
