From left to right: full light curves from the exposure starting time, partial light curves, Lomb–Scargle periodograms with n of 1, and phased light curves of the NEOs whose rotational periods are derived with high reliability. Solid, dashed, and dot–dashed horizontal lines in the periodograms show |$90.0\%$|⁠, |$99.0\%$|⁠, and |$99.9\%$| confidence levels, respectively. Confidence lines of some NEOs with strong peaks are hard to see due to scale effects. Dashed lines in the phased light curves show the model curves. Twice the rotational periods are adopted as time ranges of the partial light curves.
