Radial velocities of the stellar surface regions occulted by WASP-121b as a function of orbital phase. Horizontal bars show the exposure durations. The black curve is the best-fit reloaded RM model (indistinguishable between the low- and high- i_* solutions) to the three visits. Dashed vertical lines are the transit contacts. The horizontal dashed line highlights the stellar rest velocity, which is found along the projected stellar spin axis. Upper panel: local RVs in individual Visits 1 (red), 2 (gold), and 3 (blue). Bottom panel: local RVs derived from the CCF_loc binned over the three visits, shown separately for the sake of clarity.
