Hi,Rooters

I want to fit "Leaf" and get its parameter.
This is my program.

  TFile *f = new TFile("381run.root");
  TTree *tree = (TTree*)f.Get("tree");
  tree->Fit("gaus","leaf");
  TF1 *fit0 = tree->Fit("gaus","leaf");
  Double_t pedestal0 = fit0->GetParameter(1);
  cout << pedestal0 << endl;

Executing it, returned the error message.
Error: Incorrect assignment to fit0, wrong type 'Int_t'

How can I avoid the trouble ?
