Folding time series data

From our newly created periodogram window we can find the best fit period and fold our original data around this value. In the periodogram window select the Operations=>Find Best Period item. This will automatically find and mark (with a red line) the best period in your Fourier Transform.

You can now select the newly activated Operations=>Fold around Best Period item in the periodogram window, aloowing you to either fold the data, or fold and bin-up the data. The best fit period will be inserted by FROG in the Fold Time Series dialog, along with an arbitarily chosen zero point, and (if necessary) a suggested number of bins.

The folded time series will be labelled Time Series 2. Inspecting the meta-data for the series shows that it derived from Time Series 1, our orginal series.
