Detrended RV time series folded according to the period of TOI-5624b (top-left), TOI-5624c (top-right), TOI-5624d (middleleft), TOI-5624e (middle-right), and TOI-5624f (bottom-left) after removing the Keplerian signals of the other planets as inferred from the MCMCI analysis. The marker colour distinguishes the two different instruments (light blue for HARPS-N and orange for SOPHIE), while the red line represents the inferred model. The jitter contribution in the error bars is highlighted in grey. The RV semi-amplitudes are measured at the 6.9, 2.5, 2.2, 3.1, and 3.5σ level for planets b, c, d, e, and f, respectively.
