Zoom-in plots of HCS crossings W2−W5 at Wind, observed within the sheath. From top to bottom panels: magnetic field magnitude (black) and components in RTN coordinates (blue: B_R; green: B_T; red: B_N), solar wind velocity components in RTN coordinates (blue: V_R–400 km s⁻¹; green: V_T; red: V_N), density, magnetic field azimuth and latitude angles (dark blue: Wind, light blue: ACE; the ACE data is not time-shifted), and pitch angle distribution of 265 eV electrons. In the azimuth angle plot, the two dashed-dotted horizontal lines indicate the Parker spiral direction and solid horizontal lines indicate the division between towards and away sectors.
