    44<h4>Simultaneous Fit</h4> 
    55<p> 
    6         Can only happen with more than 2 data select with their associated model. 
    7         Can only operate with the park engine selected <b>Fitting</b> on the menu. 
    8         check <b> park</b>. 
     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.

    17         Highlight the data to fit. Select from the context menu <b>Select Data for fitting</b>. 
    18         A new tab with the name of the data selected will appears. Select a model used for the fit 
    19         from the combo box. Model's parameters will be display.Set initial parameters if need. 
    20         Check at least one parameter to fit.Go to <b>Simultaneous Fit</b> and check at least 2 
    21         models name to fit.Click on <b> constraint fit </b> button. results will be displayed on  
    22         tabs corresponding to each model select. 
     18        Assuming some FitPage 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.

    2626<h5><a name="constraint">Simultaneous Fit with constraint</a></h5> 
    2727<p> 
    28         Perform <a href="#noconstraint">Simultaneous Fit without constraint</a> step. 
    2928        Enter constraint in the text control next to  <b>constraint fit</b> button. 
    3029        Constraint should be of type model1 parameter name = f(model2 parameter name)for example, M0.radius=2*M1.radius. 
    3130        Many constraints can be entered for a single fit.Each of them should be separated  
    3231        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.
