CCF (left) and K_p–V_sys (center) maps for Ti I and Fe I. The horizontal white lines in CCF maps correspond to the T1 and T4 contact points, while the cyan dash dotted and gold dotted lines mark the expected planetary K_p and -K_p of the injected signals, respectively. The white slanted line corresponds to the Doppler shadow curve. Cyan and gold arrows in K_p–V_sys maps point toward K_p and -K_p , respectively. Orange dash dotted and white dotted pointers point toward the minimum value of the maps between RV [−40, +40] km s⁻¹, K_p [100,200] km s⁻¹and that between RV [−40, +40] km s⁻¹, K_p [−200, −100] km s⁻¹, respectively. The red and navy lines in the last column are the 1D projection of the Kp– V_sys maps evaluated at the minima found around the theoretical and injected K_p .
