    354355The objective of model-fitting is to find a *physically-plausible* model, and set 
     
    373374fit of the theory to the experimental data improves the value of 'chi2/Npts' will 
    374375decrease. A good model fit should easily produce values of 'chi2/Npts' that are 
    375 close to zero, and certainly <100.
