Left panel: maximum S/N versus velocities at the measured K_p (blue curve). In red, the best-fit Gaussian to the Fe cross-correlation peak, whose centroid results blueshifted by −5.54 ± 0.44 km/s with respect to zero km/s. The positive peaks around ~40 km s⁻¹, ~−60 km s⁻¹, and the negative peak at ~−20 km s⁻¹ are artefacts of the Rossiter-McLaughlin correction and not statistical fluctuations. Right panel: ΔK_p−v_sys diagram. The ΔK_p is calculated as ΔK_p = K_p − K_p,measured (Wardenier et al. 2023). The black dashed lines denote the expected v_sys and K_p from Prinoth et al. (2023) (i.e. K_p = 200.7 km s⁻¹). Features around +50 and −50 km/s are residuals of the Rossiter-McLaughlin correction fitting and not due statistical fluctuations (Section 4.3.1).
