S/N maps of Fe for ESPaDOnS (left panel) and a combination of all instruments (CARMENES, HARPS-N and ESPaDOnS; right panel). The detection significance peaks in both cases at K_p = 225.0 km s⁻¹ and Δv = 0.0 km s⁻¹ with a S/N value of 6.2 and 7.3, respectively. The peak coordinates in the S/N maps are indicated by the yellow dashed lines; cross-sections of the S/N peaks are reported in the horizontal and vertical panels.
