Laser ultrasonics data for Alpine Fault cataclasite

This item contains the raw waveform data for a cataclasite sample, 1a842. Each .npy file contains all the experimental data, including the waveforms (of the trigger channel and data channel) and the angular positions of the rotation stage. Confining pressures for these experiments ranged from 1MPa to 16MPa, as stated in the filename. The data can be opened using the Python NumPy library.<br>Also included are csv files which contain the arrival time picks of the P-wave in each waveform for each pressure.<br>One example experimental configuration file is included as config.json. This describes the experimental setup at 1MPa, and is identical to the config files at other pressures.<br>Finally, the 1a842_rp_data.p is a Python pickle dictionary which contains values of important variables for this sample, calculated from the experimental data. These include fast and slow velocities, density, diameter, anisotropy at all pressures, etc.<br>All data viewing of data, plotting, and analysis was performed with the Python PlaceScan package, available at https://github.com/jsimpsonUoA/PlaceScan. All experimental data was acquired with PLACE, the lab automation software (see https://github.com/PALab/place).

本数据集包含碎裂岩（cataclasite）样品1a842的原始波形数据。每个.npy格式文件均存储完整实验数据，涵盖触发通道与数据通道的波形信号，以及旋转台的角位置信息。如文件名所示，本次实验的围压范围为1MPa至16MPa，该数据可通过Python的NumPy库读取。
本数据集还附带CSV格式文件，记录了各围压下各波形的P波初至拾取结果。
此外包含一份实验配置示例文件config.json，该文件描述了1MPa围压下的实验装置参数，与其他围压对应的配置文件完全一致。
1a842_rp_data.p为Python pickle格式字典文件，存储了基于本实验数据计算得到的该样品的关键参数值，涵盖各围压下的纵波快慢速度、密度、直径、各向异性等内容。
所有数据查看、绘图与分析工作均通过Python的PlaceScan包完成，该工具包可从https://github.com/jsimpsonUoA/PlaceScan获取。所有实验数据均通过实验室自动化软件PLACE采集，相关软件获取地址为https://github.com/PALab/place。
