Detection of Fe with HARPS-N. Panel a: CCF map in the planetary rest frame (aligned using K_p = 225.0 km s⁻¹). The vertical trail indicated with white lines is the planetary Fe signal. The two horizontal dashed lines indicate the beginning and end of secondary eclipse. Panel b: signal-to-noise ratio map. The peak coordinates in the S/N map are indicated bythe yellow dashed lines. Cross-sections of the S/N map are shown in the horizontal and vertical panels.
