Cross-correlation and K_p-V_sys maps of Na I, Ca I, and Fe I obtained with the Kitzmann et al. (2023) templates at 2000K. In the first column the CCF are depicted in terms of ppm. The dotted horizontal lines indicate the T1 and T4 contact points, while the red dashed line is the planetary trace. The Doppler shadow follows the white slanted line. Second columns are the K_p-V_sys maps. The planetary signal is expected to be limited between the green pointer in the middle of the figures, while the red lines point at the minimum value of the K_p-V_sys between K_p 75 km s⁻¹, 125 km s⁻¹ and RV -50 km s⁻¹, +50 km s⁻¹. The last column is the K_p-V_sys 1D map evaluated at the K_p minimum value. The grey region is the 3σ edge, while the vertical navy dashed line refers to the RV 0 km s⁻¹.
