Multiple Curves/Multiple PeaksExpand Multiple Curves/Multiple Peaks Fitting Multiple Peaks with Replicas in the Nonlinear Curve Fit Dialog

When fitting multiple peaks curves, you can fit your data to some of the built-in peak functions by replicating the function into several "copies", each of which may have different parameters. You can customize these settings in the Settings tab, Advance page, Fit Control: Replica branch:

Fitting Multiple Peaks with Replicas-1.png

Use this feature if you believe that your data to contain multiple peaks of the same sort (e.g. Lorentzian) but different centers and/or widths. If the function you have selected does not support replications, this branch is disabled.
