A Model function is used to visualize how one or more calculated periods fit the observations. It only exists for Observations Windows analysed through the CLEANest period analysis method, and can be reached through the CLEANest Workbench. The Model function is explained in full detail as part of Tutorial 4 - Finding multiple periods using CLEANest
