Question C1:
You can run the following session:
root [] TFile f("c1.root");
root [] c1->Draw();
root [] TH1F *hdmd =
(TH1F*)c1->GetPrimitive("hdmd");
root [] TF1 *f5 =
hdmd->GetFunction("f5");
root [] double hint = hdmd->Integral();
root [] double fint = f5->Integral(0.139,0.170);
root [] double ratio = fint/hint
