(a) HARPS RV variations in the solar rest frame, corrected for relativistic Doppler effects (but not yet corrected for Vesta's axial rotation). (b) HARPS RV variations of the Sun as a star (after removing the RV contribution of Vesta's axial rotation). (c) Nightly binned HARPS RV variations of the Sun as a star – note the change in scale on the y-axis. The values for each time series are provided in the Supplementary Files that are available online.
