Hi,
Is there any method extracting components which are convoluted by RooFFTConvPdf?
I used RooFFTConvPdf to convolute a Gaussian pdf with Breit-Wigner pdf and I want to see each fit component but I don’t know how to do.
I tried like this:
...
RooBreitWigner bw("bw", "bw", x, bwmean, bwwidth);
...
RooGaussian gauss("gauss", "gauss", x, gmean, gsigma);
...
RooFFTConvPdf signal("signal", "signal", x, bw, gauss);
signal.fitTo(data, Extended());
...
signal.plotOn(frame);
signal.plotOn(frame, Components("bw"), LineStyle(kDashed));
...
I expected that it shows fitted Breit-Wigner component with dashed line but it shows convoluted one. (Solid line and dashed line shows same shape)
How can I plot fitted components in convoluted pdf?
