Description
Parker Solar Probe SPAN-I Alpha particle differential energy flux (contaminated by Protons) dataset covers 8 defector settings, 32 energies, and 8 angles. The log spaced energy range covers 21.0 eV to 17.6 keV. The field of view covers the entire sky except for the region obscured by the heat shield.
Due to heat shield, the centroid of the solar wind alpha particle distribution is typically only observed around perihelion. The mode of the cadence is about 3.5 seconds, with smaller cadence of about 1.7 seconds around perihelion.
