Data Sets S1

There are two folders in the Data Sets S1. Observed and synthetic waveforms which are normalized are in the folder named ‘Waveform matching result’. In this folder, each .mat file denotes each event and consists of the event information (‘eventData’), observed traces (‘Traces.data’), and synthetic waveforms (‘ts_run.data’) with relative attenuation measurements (‘ts_run.tStar_WF’). The 2-D attenuation model and model standard deviation for plotting are included in the folder named ‘model for plotting’.
