Solar wind magnetic field and plasma data as measured by the PSP during the first reconnection exhaust within the sheath (the first magenta line in Figure 1). From top to bottom: a) Magnetic field magnitude (black) and three magnetic field components in RTN (blue: B_R, green: B_T, pink: B_N), b) azimuth RTN angle of the magnetic field, c) three solar wind velocity components in RTN (blue: V_R − 300 km/s, green: V_T, pink: V_N, d) solar density and e) solar wind temperature, f) the PVIs for three different MHD timescales τ (14 s, 56 s, and 223 s).
