I made a simpler version of my problem. I forgot to mention
that I am running Root 3.03/09 on Linux
#include "TH2.h";
#include "TH1.h";
TH2D *exam;
void Simple(){
exam = new TH2D("exam","demo",36,-1.8,1.8,36,-180,180);
for (int i=0;i<36;i++)
{
for (int j=0;j<36;j++)
{
exam->SetBinContent(i+1,j+1,100000);
}
}
exam->Sumw2();
cout << " bin 10,10 = " << exam->GetBinContent(10,10) <<" " <<
exam->GetBinError(10,10) <<endl;
exam->ProjectionX("pro1",10,10,"e");
cout << "projection " << pro1->GetBinContent(10) << " " <<
pro1->GetBinError(10) << endl;
pro1->Draw();
return();
}
This code prints

He was screaming in agony. Fortunately I speak it fluently.
