Frictional healing of anhydrite-bearing faults imaged by ultrasonic waves

Experimental datasets for the manuscript: Frictional healing of anhydrite-bearing faults imaged by ultrasonic waves. Files ending with data_rp contain the friction experiment time-series data used in this study. These files can be opened as tab-delimited CSV files, using \t as the separator. Column names and measurement units are reported in the file headers. Files containing coulomb include the data points used to construct the Coulomb failure envelopes. Files named rsf_data_table contain the results of the rate-and-state friction inversions performed on velocity-step experiments. Files named shs_data contain the data obtained from slide-hold-slide experiments. Files containing deltavelocity and deltaamplitude include the datasets used to quantify the increase in S-wave velocity and amplitude during hold periods. Files containing bscan.tsv, together with the corresponding experiment number, contain the raw ultrasonic waveform data. Each file refers to a specific portion of an experiment. For example, 004_hold_10_sec.bscan_s0233 contains the waveforms recorded during the slide-hold-slide sequence with a hold duration of 10 s. These files are two-dimensional tab-separated value matrices. One dimension corresponds to the waveform number, while the other corresponds to the time samples within each individual waveform.
