Hello,
I am doing Analysis using Draw, and I wonder how could I save the errors.
Could I use the sumw2() somehow?
I know that the trees on which I am running have errors.
chain_data->Draw("probe_pt>>data_2_2","abs(probe_eta)>2.2 ");
TH1F *data_2_2 = (TH1F*)gPad->GetPrimitive("data_2_2");
data_2_2->Write();
Thank you in advance,
Des
