Significance for different bin sizes and periods in phase-folding periodicity search. The x-axis represents the bin size, and the y-axis shows the period. The color intensity indicates the corresponding significance, which reflects the significance of the periodicity detection for each trial. It is evident that periods around ∼200 days are relatively significant for reasonable bin sizes.
