Cross-correlation results of both nights combined for Ca I, Fe I, Fe II, and V I (from left to right, respectively). Top panel: cross-correlation maps of the three different species. Bottom panel: average of the in-transit cross-correlation values in the planet rest frame between the first and fourth contacts. The y-axis is shown in S/N units, where negative values mean anti-correlation (see the cross-correlation coefficients in the colour bar).
