class AliDielectronHFhelper: public TNamed

Dielectron Histogram framework helper



A helper class to extract objects(histograms and/or profiles) from
a AliDielctronHF array of objects.


How to use it:

  AliDielectronHFhelper *hf = new AliDielectronHFhelper("path/to/the/output/file.root", "ConfigName");
  // print the structure
  hf->Print();

  //apply some cuts and print them
  hf->SetRangeUser("cut1name",cutmin1,cutmax1);
  hf->SetRangeUser(AliDielectronVarManager::kPt,ptmin,ptmax);
  hf->PrintCuts();

  // collect 1-,2- or 3-dim histograms or profiles with error option (default:"")
  TObjArray *arrHists = hf->CollectHistos(AliDielectronVarManager::kM);
  TObjArray *arrProfs = hf->CollectProfiles("",AliDielectronVarManager::kM,AliDielectronVarManager::kPt);

  // then you are left with an array of histograms for all pair types or MC signals
