S/N maps after six and five consecutive SYSREM iterations with CARMENES for TiO and Fe, respectively. We get S/N significance levels of 4.9 for TiO and 5.7 for Fe. The peak coordinates in the S/N map are indicated by the yellow dashed lines. Cross-sections of the S/N peaks are reported in the horizontal and vertical panels. The horizontal panels also correspond to the collapsed CCF maps in Fig. 5. The Fe signal is consistent with the expected K_p value; the TiO peak is found with an offset of roughly +17 km s⁻¹.
