Global Nonlinear Least-Squares Equilibrium Analysis:

Part 2: Model Selection Previous: Setting up a Fitting Project Next: Scan Diagnostics

After importing experimental data into the Global Fitting Control panel, you need to select a model to be fit. Models in UltraScan are indexed, the index for each model, which is used in naming associated datafiles, is listed here. Clicking on the "Select Model" button you can select from a number of predefined models as well as define your own models. After selecting a model, an information page will be shown, which will indicate the equation used for this model, and identify all parameters used. Parameters with a (*) can be floated so that an optimum value will be determined by the nonlinear least squares fitting algorithm. Simply click on the "OK" button to continue. Three of the model selections require additional user input:
