Fig. 1
LS periodogram spectrum (green line) of NGC 5408 X-1. The red dashed curve represents the theoretical AR(1) power spectrum, and the blue dot-dashed curve marks the 99.74% (or 3σ) statistical confidence level derived from Monte Carlo simulations performed 5000 times. Three peaks (P1, P2, and P3) are above the 99.74% statistical significance level.
