Plots generated by AliasFinder for the daily (top) and yearly (bottom) aliases for the 15.6 d signal. Each row illustrates the results for one simulated frequency, as indicated by the dashed blue vertical line. Each column is centered on a frequency window corresponding to the simulated frequencies. The red line represents the periodogram of the original data set, whereas the black line is the median of the simulations, and the gray shaded regions depict the interquartile range and the confidence range of 90% and 99% of the simulations. The clock diagrams indicate the phase.
