{


  TF2 *f2 = new TF2("f2","(0.045850618*pow(sin(y),2))/(pow(x,2));bla;bla",200.0E-9,700.0E-9,0.0,0.02617);
  // gStyle->SetOptTitle(kFALSE);
   
  f2->SetTitle("Differential Cherenkov Photon Flux");
//  f2->GetYmin(0.0);
//  f2->GetYmax(1.5);
//  f2->GetXmin(200E-9);
//  f2->GetXmax(600E-9);
  TCanvas *c3 = new TCanvas("c3","Peak Flux vs Mean Flux",400,10,700,500);
  gStyle->SetPalette(1,0);
  c3->SetFillColor(0);
  // c3->SetLogx();
  // c3->SetLogy();
