MMS 4 Energetic Particle Detector, Energetic Ion Spectrometer (EPD-EIS) Pulse Height by Time of Flight, Level 2 (L2), Survey Mode, 2.42 s Data

Energetic Particle Detector (EPD), Energetic Ion Spectrometer (EPD EIS) Pulse Height by Time of Flight, Level 2, Quick-Look Survey, 2.42 s Data. The EIS provides ion composition measurements (protons versus oxygen ions) and angular distributions over the energy range from approximately 45 to 500 keV.

高能粒子探测器（Energetic Particle Detector, EPD）的高能离子光谱仪（Energetic Ion Spectrometer, EPD EIS）所产出的基于飞行时间的脉冲高度数据集，属于二级数据产品，为快速概览勘测数据，采样间隔为2.42秒。该高能离子光谱仪可在约45至500千电子伏的能量范围内开展离子成分测量（区分质子与氧离子）并获取粒子角分布数据。
