Nightly binned time series (left panels) and their periodograms (right panels) of AU Mic extracted with raccoon. From top to bottom they are RV, BIS, FWHM, and CON. For the CON, one obvious outlier is not in this diagram. Dashed blue horizontal lines indicate FAP levels of 0.1, 1, and 10%, and the vertical orange lines indicate the frequency of the rotation period of 4.9 days and its second harmonic. The vertical green lines mark the periods of the two planetary companions.
