The sheath at Solar Orbiter, Wind and BepiColombo. From top to bottom panels: B-field magnitude and components in RTN coordinates; RTN B-field azimuth angle; RTN B-field latitude angle; wavelet PSD of B-field fluctuations at 1−8 mHz; normalised B-field fluctuation amplitude at three timescales; and fluctuation compressbility. The vertical lines as same as in Fig. 8, the shock is shown by the solid black line and the magnetic cloud leading edge time (LE1) by the solid red line, and the magenta lines indicate relatively sharp field changes of interest. Orange shading indicates the location of a small-scale flux rope identified within the sheath at each spacecraft, and cyan lines show Gold-Hoyle flux rope fits to these intervals.
