MMS 4 Fast Plasma Investigation, Dual Electron Spectrometer (FPI, DES) Instrument Distributions, Level 2 (L2), Burst Mode, 30 ms Data

The Fast Plasma Instrument (FPI) usually Operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at Burst (30/150 ms for DES/DIS) Resolution in this Mode. Data are also made available at Survey (4.5 s, etc.) Resolution. Per Mission Design, not all Burst Resolution Data are downlinked, but all Survey Data are downlinked. This Product contains Phase Space Distribution Maps of those Burst Resolution Data selected for downlink. In particular, the (highest possible Quality at the Time of Release) corrected/converted "Burst Sky Map" Distributions are reported with Time Stamps and other Annotation characterizing the State of the Instrument System at the indicated Time.

当前任务阶段中，快速等离子体仪器（Fast Plasma Instrument, FPI）通常在磁层多尺度任务（Magnetospheric Multiscale, MMS）的感兴趣区域（Region Of Interest, ROI）内运行于快速勘测（Fast Survey, FS）模式。该模式下的数据以爆发分辨率采集，其中DES与DIS的采样时长分别为30毫秒与150毫秒。数据同时也会以勘测分辨率（约4.5秒及其他时长）提供。依据任务设计要求，并非所有爆发分辨率数据均可下行传输，但所有勘测分辨率数据均会完成下行传输。本数据集包含经筛选用于下行传输的爆发分辨率数据的相空间分布图谱。具体而言，本数据集将展示发布时所能达到的最高质量的经校正与转换后的"爆发天图"分布数据，并附带时间戳，以及用于表征指定时刻仪器系统状态的各类标注信息。
