+ --> SetOptFit(1111111)
+            function "[3]*exp(x/2.19703)*(1+[2]*cos(x*[0]+[1]))" was fitted
+            Asymmetry = 0.42
+
+To study pileup background --> natural decay of muons is required.
+This was done in the file 14460:
+
+root [10] TFile* f=new TFile("data/his_14460_14460a.v1190.root")
+root [11] hdet_time20_6->Draw()            // condition 6 goodEvent_det
+ --> SetOptFit(1111111)
+           function "[0]*exp(-x/2.19703)+[1]" was fitted
+ --> Remember that par0 = 375.8  (Normalisation)
+ --> Background from the fit:  par1/par0 = 4.4 / 375.8 = 1.2%
+
+root [12] hdet_time20_rotref_6->Draw()     // condition 6 goodEvent_det
+ --> SetOptFit(1111111)
+          function "[2]*cos(x*[0]+[1]" is fitted
+ --> Asymmetry = 2* par2/Normalisation = 2 * 78.5 / 375.8 = 0.418
+
+2nd way how to extract pileup background:
+root [13] hdet_time10_bgr3_6->Draw()       // condition 6 goodEvent_det
+ --> SetOptFit(1111111)
+ --> background = par0/Normalisation = 4.9 / 375.8 = 1.3%
+
+3rd way how to extract background:     
+root [14] hdet_time10_bgr1_9->Draw()      // condition 9 pileupEvent
+ --> SetOptFit(1111111)
+ --> background = par0/Normalisation = 4.5 / 375.8 = 1.2%
+
+Where to the muons and pileup muons stop? :
+root [28] humanDecayHistograms_6->Draw()         //  <--- accepted events
+root [29] humanDecayHistograms_9->Draw()         //  <--- mu1 for pileup events
+root [30] humanDecayPileupHistograms_9->Draw()   //  <--- mu2 for pileup events
