MMS 4 Fast Plasma Investigation, Dual Ion Spectrometer (FPI, DIS) Instrument Distributions, Level 2 (L2), Burst Mode, 0.15 s 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.

快速等离子体仪器（Fast Plasma Instrument, FPI）在当前任务阶段的磁层多尺度任务（Magnetospheric Multiscale, MMS）感兴趣区域（Region Of Interest, ROI）中通常以快速巡天（Fast Survey, FS）模式运行。该模式下的数据以突发分辨率（Burst Resolution）采集，其中DES与DIS的采样时长分别为30 ms与150 ms。此外，该仪器还提供巡天分辨率（Survey Resolution）版本的数据，采样时长约为4.5秒及其他档位。根据任务设计规范，并非所有突发分辨率数据均会下传，但所有巡天分辨率数据均可完成下传。本产品包含经筛选用于下传的突发分辨率数据的相空间分布图（Phase Space Distribution Maps）。具体而言，本数据集将呈现发布时所能达到的最高质量的经校正与转换后的“突发视场天图（Burst Sky Map）”分布数据，并附带时间戳（Time Stamps）以及用于表征指定时刻仪器系统运行状态的各类标注信息。
