GLS periodograms of the SOPHIE RV time series, the residuals of the best-fit Keplerian model (from Sect. 3.2), the BIS, and the window function. For TOI-1199 (left panel) and TOI-1273 (right panel), the image shows the computed power spectrum of the GLS. In the RVs, the highest peak matches the transit period of the planet candidates, but the same signal is not present in the residuals, the BIS, or the window function. The analytical false alarm probability threshold of 1% is shown.
