Top: cross-correlation residuals map of FeI during the observations. The horizontal red-dashed lines show first (T1) and last (T4) transit contacts and the white-dashed lines show the expected planetary trail. Bottom: cross-correlation values at 0 km s⁻¹ vs. time for Fe I (black), that is, a vertical cut on the top panel. Also shown is the cross-correlation evolution but for the Ca I (blue), showing a similar time evolution.
