Caption: Figure 6.
Fraction of light curves meeting the 99% confidence threshold as a function of light-curve amplitude and rotational period. Each bin shows the fraction of objects whose Lomb–Scargle periodogram structure indicates high confidence in the recovered period. Recovery confidence decreases significantly at lower amplitudes, where weaker variability reduces the reliability of period identification.
