### 03/30 : modifications ###
1) too many histograms initally. 
This version has  320*2 + 320*2 + 320 + 6 = 1606 TH1D;

  TH1S  *m_cluster_SN_sideP[320];   // signal/noise of clusters per wafer P-side
  TH1S  *m_cluster_Size_sideP[320]; // # of strips of clusters per wafer P-side
  TH1S  *m_cluster_SN_sideN[320]; // signal/noise of clusters per wafer N-side
  TH1S  *m_cluster_Size_sideN[320]; // # of strips of clusters per wafer N-side
  TH2S  *m_matchisto[320]; // charge matching per wafer
  TH2S  *globalMatchisto; // total charge matching
  TH1S  *globalDeviation; // total deviation : chargeP - chargeN
  TH2F  *globalPosition; // global poisitons
  TH2F  *localPosition; // local positions
  TH2F  *rphiZ; // r-phi plot of points
  TH2S  *LadderWaferHits; // # of points per wafer
