A frequency Lomb–Scargle periodogram of the π Men c OC plot. The false-alarm probabilities (FAP) = 0.1, 0.05, and 0.01, measurements conditioned on the assumption of the null hypothesis of no signal, are shown as horizontal lines. Note that none of the periodogram peaks rise above any of the FAP thresholds, and as such, our OC plot is consistent with a lack of TTVs.
