Fast-wind region and rarefaction region of the March 2017 stream. From top to bottom: solar wind speed at a time resolution of 6 s (panel a), values computed in a one-hour moving window of the kinetic energy in semilogarithmic scale (panel b), magnetic energy in semilogarithmic scale (panel c), density compressibility in semilogarithmic scale (panel d), compressibility of the magnetic field magnitude in semilogarithmic scale (panel e), compressibility of magnetic field fluctuations in semilogarithmic scale (panel f), normalized cross-helicity (panel g), and normalized residual energy (panel h). The downward spike in correspondence of doy 65 is an edge effect due to the gap of about 2 h.
