CCF maps from CARMENES aligned to the rest frame consistent with the maximum K_p values (i.e., 248.0 km s⁻¹ for TiO and 228.0 km s⁻¹ for Fe; see Fig. 6). We indicate the TiO signature with the vertical dashed lines. The two horizontal dashed lines indicate the beginning and end of the secondary eclipse. We masked the phase interval where the TiO signal is below the noise level (see Sect. 5.2). Also the radial velocity domain of residual stellar Fe lines was masked (see Sect. 4.2). The wider Fe trail when compared to TiO is likely caused by a different degree of rotational broadening, which hints at a global distribution of Fe and localized TiO in the atmosphere of WASP-33b.
