Example of a clean SIR and CIR event observed by PSP showing: (a) radial H⁺ velocity, (b) tangential H⁺ velocity deflection, (c) H⁺ density, (d) H⁺ temperature, (e) specific entropy argument, (f) sum of H⁺ plasma and magnetic pressure, (g) magnetic field magnitude, (h) magnetic Θ_RTN, (i) magnetic Φ_RTN, and (j) 30–586 keV suprathermal ion count rate. The blue and orange vertical dashed lines indicate where the radial velocity transitions from slow to fast solar wind. The red dotted line denotes the pressure peak within the velocity increase.
