Proton-Contaminated Alpha Differential Energy Flux measured by the PSP SPAN-Ion Instrument

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.

帕克太阳探测器 SPAN-I 型阿尔法粒子微分能量通量（受质子污染）数据集涵盖了8种缺陷设置、32个能量级别和8个角度。对数刻度的能量范围覆盖了从21.0电子伏特至17.6千电子伏特。视场覆盖了整个天空，除了被热护盾遮挡的区域。由于热护盾的存在，太阳风阿尔法粒子分布的重心通常仅在近日点附近被观测到。数据采集频率的模态约为3.5秒，而在近日点附近则存在约1.7秒的较小采集频率。
