Edit .h & .cxx files

• Edit St_tcl_Maker.h and put in:
  • at list of classes it uses: class TH1F;
  • under private methods: void MakeHistograms(); //Histograms for tpc clustering (this is mine)
  • under protected methods: TH1F *m_z_of_hits; //! z distribution of hits

• Edit St_tcl_Maker.cxx and put in:
  • at list of includes: #include "TH1.h”
  • at end of Init method: // Create Histograms
      m_z_of_hits = new TH1F("zofhits","z dist of hist",50,-200.,200.);   return StMaker::Init();
  • at end of Make method: //Histograms
      MakeHistograms(); // clustering histograms
  • then write the MakeHistograms method:
    void St_tcl_Maker::MakeHistograms() {
// Create an iterator
St_DataSetIter tpc_hits(m_DataSet);
//Get the table:
St_tcl_tphit *tphh = 0;
tphh = (St_tcl_tphit *) tpc_hits.Find("tphit");
// cout << " **** NOW MAKING HISTOGRAMS FOR TCL !!!!! " << endl;
if (tphh) {
tcl_tphit_st *r = tphh->GetTable();
for(Int_t i=0; i<tphh->GetNRows();i++,r++){
Float_t zofhit = r->z;
m_z_of_hits->Fill(zofhit);
}
}
}
