Cross-correlation signal made from a model that includes Na, K, Fe, V, and TiO with the combined spectrum from the three epochs. Frames were combined considering the Doppler shift of the planet. Positive values represent a positive correlation with the model, whereas negative values are anti-correlated. The units are in given as S/N with respect to the overall signal. The velocity reference of the star is marked as a blue line at −10.63 km/s. The x-axis indicates the offset relative to the line of sight velocity of the stellar system (V_LOS ).
