The data set provides 1 hr averages of He⁺², phase space density as a function of V/Vsw in 51 velocity ranges, where V and Vsw are the PUI particle speed and bulk speed of solar wind protons, respectively.}, publisher={NASA Space Physics Data Facility}, author={Galvin, Antoinette B.}, year={2023}, language={en} }
