    352352difference between the experimental data and the theory) at the same X-data values.

    355354The objective of model-fitting is to find a *physically-plausible* model, and set 
     
    374373fit of the theory to the experimental data improves the value of 'chi2/Npts' will 
    375374decrease. A good model fit should easily produce values of 'chi2/Npts' that are 
    376 close to zero, and certainly <100. See :ref:`Assessing_Fit_Quality`.

    398397*Send To Fitting*. Either way, the result should be that for *n* data sets you have 
    3993982\ *n* graphs (*n* of the data and model fit, and *n* of the resulting residuals). But

    441439Note that the chi2/Npts value returned is the SUM of the chi2/Npts of each fit. To 
    442440see the chi2/Npts value for a specific *FitPage*, click the *Compute* button at the 
    443 bottom of that *FitPage* to recalculate. Also see :ref:`Assessing_Fit_Quality`.
