Hi, I am performing a 2D fit in RooFit.
Relevant commands used to fit are below:
RooFitResult* fitres =mdzdel1.fitTo(*ds1,Extended(kTRUE),Minos(1),NumCPU(4),Save());
I am calling MINUIT twice and using MINOS for error calculation.
I use paramOn to show parameters on frame but it doesn’t show the results from latest Migrad converged instance but earlier MIGRAD converged instance after which a new minimum is found.
How do I fix it to show the parameters from final MIGRAD converged instance also matching the MINOS results ?
I am attaching the log file. Its very big , but to get the point better strategy is to look for word “converged” in the log file.
I am also attaching the fit projection with paramOn the frame, compare to the final results in attached log file , they don’t match.signal_2d_mdz.pdf (23.7 KB)
Please let me know how to fix it.
