The root directory of the supplementary data contains a README.pdf file describing the data observation, along with Comma-Separated Values (CSV) files corresponding for each Baseline and Diagnostic measurement at 13 different temperatures in [-10, 50] °C range with 5 °C step across all transducer paths (e.g., 1-7, 1-9, ..., 7-11) for impact I1 and impact I2 at 40 and 50 kHz of excitation frequency. The directory structure is as follows:

/
├─ README.pdf
├─ 01_Baseline_40kHz_I1.csv
├─ 01_Diagnostic_40kHz_I1.csv
├─ 02_Baseline_50kHz_I1.csv
├─ 02_Diagnostic_50kHz_I1.csv
├─ 03_Baseline_40kHz_I2.csv
├─ 03_Diagnostic_40kHz_I2.csv
├─ 04_Baseline_50kHz_I2.csv
└─ 04_Diagnostic_50kHz_I2.csv*
├─ row id 1 (column-wise notation): P01-07_T-10C, ..., P07-11_T50C
├─ row id 2 (1st time sample): 164E-15, ..., 1.80E-14
├─ row id 3 (2nd time sample): -7.4727, ..., -5.5183
├─ . . .
└─ row id 6001 (6000th time sample): -70.667, ..., -57.333

* Column-wise structure of signal for specific sensor path (P) and temperature (T) in °C for 04_Diagnostic_50kHz_I2.csv as an example. Each time sample represents the amplitude value in mV.
