How do I use getVal(nset) and getNorm(nset) to read/generate normalized values from a model pdf?
I know from other forum messages and google that getVal(0) is unnormalized but can’t find any examples that show its proper use.
Currently getVal(0) is working and I can find the peaks I’m looking for, but I need to find the multiplier.
Does “nset” refer to the model or the data or the results of Minuit?
Double_t gnorm = gauss.getNorm(RooArgSet( ??? )); // simple case
Is there a tutorial example?
