Empirical velocity-space diffusion coefficients from PSP proton VDFs match scale-dependent intermittent stochastic heating and rule out parallel-ICW resonant heating and helicity-barrier SH in a sub-Alfvénic stream.
See Supplemental Material at https://journals.aps.org/prl/supplemental/10.1103/s4q4- v7rm for a derivation of the empirical calculation made from the spacecraft observations

Direct Measurement of Diffusion Coefficients: Evidence for Diffusive Stochastic Heating in Collisionless Plasmas
Empirical velocity-space diffusion coefficients from PSP proton VDFs match scale-dependent intermittent stochastic heating and rule out parallel-ICW resonant heating and helicity-barrier SH in a sub-Alfvénic stream.
