Adding and Removing Curve Fit Bands

The Select Bands dialog provides a means for adding and removing bands, modifying band parameters, performing a curve fit, and viewing results. This dialog is automatically presented when selecting Curve Fit from the Data menu. If you have closed it and wish to re-display it, click the Bands button in the Curve Fit dialog. Use What's This help for information on the individual fields.

Click the “+” and “-“ buttons to add and remove a band, respectively. The first band you add is automatically placed close to the highest peak. Subsequent bands are added to locations where there is the greatest difference between the actual data and the resultand curve, usually indicating the next highest peak.

Use the least amount of bands (peaks) that adequately describes your data. Increasing the number of bands increases the time and complexity of the fit.
