Individual MEarth datasets separated according to observational season and telescope (left panels). We also show their periodograms for longer periods (>50 days, middle panels) and the full periodograms (right panels). We mark the significant signals in grey, the period of our planet in green, and the rotational period of the star in blue, within the errors. The FAP levels of 10, 1, and 0.1% are shown by the red dashed lines.
