This fitting option enables to set a number of the constraints between the parameters of fitting(s). It requires one or more FitPages with a data and a model set for the fitting, and performs multiple fittings given by the FitPage(s). The Complex (ParkMC) FitEngine will be used automatically.
Assuming some FitPages are already set up, check the checkboxes of the model_data rows to fit.
And click the 'Fit' button.
The results will return to each FitPages.
Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits.
If one needs the chi2 value only for a page, click the 'Compute' button in the FitPage to recalculate.
Enter constraint in the text control next to constraint fit button.
Constraint should be of type model1 parameter name = f(model2 parameter name)for example, M0.radius=2*M1.radius.
Many constraints can be entered for a single fit.Each of them should be separated
by a newline charater or ";"
The easy setup can generate many constraint inputs easily when the selected two models are the same type.
Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits.
If one needs the chi2 value only for one fit, click the 'Compute' button in the FitPage to recalculate.
