Source Physics Experiment Phase 1 Large-N Array

The SPE Phase 1 Large-N array used 996 sensors within a 2km by 2.5km area. The SPE5 data set spans 2-minutes around the SPE-5 explosion. The data starts at 55 seconds before the SPE-5 detonation. The FREY data are extracted data for weight drops at 53 locations. There are multiple drop repeats at each location. Each segy file represents one weight drop.

SPE第一阶段大阵列传感器（Large-N array）在2千米×2.5千米的区域内部署了996个传感器。SPE5数据集覆盖了围绕SPE-5爆炸事件的2分钟时长区间，其数据起始时刻为SPE-5起爆前55秒。FREY数据集是从53个测点的重物投放（weight drops）实验中提取得到的，每个测点处均开展了多次重复投放实验。每个SEG-Y（segy）文件对应一次重物投放实验。
