|---|
| 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). |
|---|
| 9 | The Complex (ParkMC) FitEngine will be used automatically. |

| 18 | Assuming some FitPages are already set up, check the checkboxes of the model_data rows to fit. |
|---|
| 19 | And click the 'Fit' button. |
|---|
| 20 | The results will return to each FitPages. |
|---|
| 21 | <br/>Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits. |
|---|
| 22 | If one needs the chi2 value only for a page, click the 'Compute' button in the FitPage to recalculate. |

| 28 | Enter constraint in the text control next to <b>constraint fit</b> button. |
|---|
| 29 | Constraint should be of type model1 parameter name = f(model2 parameter name)for example, M0.radius=2*M1.radius. |
|---|
| 30 | Many constraints can be entered for a single fit.Each of them should be separated |
|---|
| 31 | by a newline charater or ";" |
|---|
| 32 | The easy setup can generate many constraint inputs easily when the selected two models are the same type. |
|---|
| 33 | <br/>Note that the chi2/Npts returned is the sum of the chi2/Npts of each fits. |
|---|
| 34 | If one needs the chi2 value only for one fit, click the 'Compute' button in the FitPage to recalculate. |
