Fitting folded data

Selecting the Operations=>Fit Data item from the Time Series 2's plot window fits the data with a $\sin()+\cos()$ function.

Here (above) we can see our original data folded around the best fit period found in our periodogram fitted with our $\sin()+\cos()$ function.

Inspecting the meta-data, using the File=>Meta data item

shows the fit parameters in more detail.

We've now walked through the basic proceedure for reading in a time series, finding the best period, and the folding and fitting around this period. However FROG has many other capabilities, so keep reading...
