This item contains the raw waveform data for a schist
sample, schist_2. 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.
Also included are csv files which contain the arrival time picks of the P-wave in each waveform for each pressure.
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.
Finally, the schist_2_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.
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
