Notes. Heliocentric distance, R; solar wind bulk speed, Vsw; number density, np; proton temperature, Tp; magnetic field magnitude, B; angle the magnetic field forms with the velocity field, ΘBV; plasma beta, β; cyclotron resonance damping, fR. For PSP at 0.33 AU (PSP2), only the average bulk speed was inserted as an indicative value since derived from poor-quality data computed from the SPC instrument.
