(3) Channel display field
The Channel display field shows the active channel (selected name and color), for which the Fit All
button applies. It is the last selected channel. If for example, you have selected rows in the Result table
belonging to channel 1, channel 2 and a cross correlation channel, the last selected channel will be
displayed and if you press Fit all selected rows will be updated. If you press Fit All, only the rows
belonging to the displayed channel will be updated.
(4) Model field
Load a suitable model from the Model pull down menu. The name of the model will be displayed in the
Model Display box. All the terms and components of the model will be displayed in a tabular form. You
can deselect and select terms by unchecking / checking the boxes on the left of each term.
After selecting a model the corresponding model will be displayed in the Fit table. All parameters
belonging to one term are listed as a block in the Parameter column, which shows the term and
parameter names.
The current parameter values are displayed in the Values column. You can edit a value by typing. The
handling of the parameter is defined in the Type column. By clicking with the left mouse button in the
respective field, a button tab becomes available. Use the arrow head to open the drop down menu.
Three options for the parameter setting will become available (Fig. 383):

− If you select Free, the parameter will be defined as free. After the fit, the field will contain the fit
result for the parameter. The start values of the parameter (initial guesses) will be calculated by an
algorithm.
− Fix allows you to fix the parameter. This is useful if you know its value from other measurements.
− Start will assign a start value to the parameter and leaves the parameter free to fit. In this case, no
initial guesses will be made.
Upper and lower values for the fit parameters can be entered in the fields of the Upper limit and Lower
limit columns. Defaults are the extreme possible values. If fit limits fall short or are exceeded, the fit will
try to find another solution or will fail.
