Periodograms of the ESPRESSO radial velocities (top) and activity indicators (second to bottom: CCF FWHM, CCF contrast, CCF bisector, H_α, log R′_HK, and Na I) for TOI-286. The vertical orange and red lines indicate the candidate planet periods for TOI-286.01 and TOI- 286.02. The green shaded area indicates 1σ around the stellar rotation period. The dotted, dashed, and solid horizontal grey lines indicate the 10%, 1%, and 0.1% FAP levels respectively.
