Data for the paper "The Complex Inner Core Boundary Beneath South America from Seismic Core Phases: Possible Elevated Topography and Fast Crystallization"

This dataset contains 261 high-quality seismic observations with clear PKiKP and PcP signals, recorded from 52 deep-focus earthquakes (depth ≥ 300 km) in the South America. The data file includes:1. Two tables:Table 1: Provides information about the seismic events and recording stations.Table 2: Contains measured data, including arrival times, amplitudes for P, PcP, and PKiKP phases, PKiKP-PcP differential travel time residuals, PKiKP/PcP amplitude ratios, and their corrected values.2. Raw waveform data in SAC format. All seismic waveform data are available through the IRIS Data Management Center (https://ds.iris.edu/ds/nodes/dmc).
