I have a spectrum (histogram) of kind TH1F called “h_tof” and I would like to fit the background using the function Background here in the documentation : root.cern.ch/root/html/TSpectru … Background
Since it outputs a TH1, that I will call for example “ambiant” I understand I need to declare it first, then use the function. I’m sorry I’m very new and this might be completely wrong, this I why I post something here
TSpectrum *s = new TSpectrum ();
TH1 *ambiant = new TH1("ambiant");
I also tried
TH1::TH1 *ambiant = new TH1::TH1("ambiant");
"this outputs : Error: Can’t call TH1::TH1(“arriereplan”) in current scope
None of them work.
Also , is there a way of evaluating this background fit afterwards at one given point? All this is of course to compute the signal to background ratio.
Thanks in advance for your help,
