SolO measurements. From top to bottom: magnetic field in RTN frame, full proton velocity (navy) and tangential velocity (blue), number density (navy), and the magnetic field magnitude (blue), E/Q-time spectrogram of the differential ion energy flux. The vertical dashed lines marked the regions boundaries, explained in the text. The dashed light blue lines, in the second from the top panel, show the trend of maximal and minimal solar wind velocities. The plot is divided into six time intervals, as discussed in the text.
