Top panel: phase—v_sys maps for the detected species H₂O (left) and CO (right) in the stellar reference frame. The red dashed line indicates the predicted velocity trail of the planet. The colour bars are expressed in standard deviations away from both planet and telluric signals (excluding the square in the K_p-V_sys map defined by K_p ∈ [0,300] and V_sys ∈ [−10,30]). Bottom panel: K_p-v_sys map for H₂O (left) and CO (right), the vertical dashed line indicates the stellar reference frame, the horizontal dashed line indicates K_p = 120 km s⁻¹. The maximum value of the map is indicated by the + symbol in black with the associated value, while the minimum is indicated by the blue cross.
