Top row: Light curves (left and central panels) and corresponding CCF (right panel) obtained using the adaptive rebinning method (10 photons per bin). Middle and bottom rows: Same configuration, but using fixed bin sizes of 1 s and 0.05 s, respectively. In each row, the left panel shows in blue the simulated signal obtained by rebinning the ToA list generated by simulating the theoretical profile shown in orange. The center panel displays the same signal, delayed by 1 s before rebinning. The right panel presents the CCF between the two simulated light curves shown in the left and central panels of the corresponding row.
