Cross-correlation functions of the observations from the two nights. Upper and middle panels: observed and modelled CCF map in the stellar rest frame, respectively. The atmospheric Fe I signal is the bright stripe that appears during out-of-eclipse. The blue dashed lines indicate the expected planetary RV during eclipse. Bottom panel: CCF map with the planetary velocity (v_p) corrected using the best-fit K_p and Δv values, and the atmospheric signal is the vertical stripe located around zero RV.
