Partial screenshot of CIRCADA-S Summary tab, comparing results from the five methods for a set of 1,000 generated time series with the user-selected characteristics. The histograms of period errors demonstrate the differences between the methods. The DWT, autocorrelation, and Lomb-Scargle produce discrete estimates with possible values determined by the sampling interval and number of cycles, while sine-fitting and MESA produce finer-grained estimates.
