4<h4>Simultaneous Fit</h4>
5<p>
6        This fitting option enables to set a number of the constraints between the parameters of fitting(s).
7        It requires one or more FitPages with a data and a model set for the fitting,
8        and performs multiple fittings given by the FitPage(s).

17        Assuming some FitPages are already set up, check the checkboxes of the model_data rows to fit.
18        And click the 'Fit' button.
19        The results will return to each FitPages.
20        <br/>Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits.
21        If one needs the chi2 value only for a page, click the 'Compute' button in the FitPage to recalculate.

27        Enter constraint in the text control next to  <b>constraint fit</b> button.
28        Constraint should be of type model1 parameter name = f(model2 parameter name)for example, M0.radius=2*M1.radius.
29        Many constraints can be entered for a single fit.Each of them should be separated
30        by a newline charater or ";"
31        The easy setup can generate many constraint inputs easily when the selected two models are the same type.
32        <br/>Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits.
33        If one needs the chi2 value only for one fit, click the 'Compute' button in the FitPage to recalculate.
