Seismic travel-time data from: Illuminating structural variability of the East Aleutian plate interface from local and teleseismic P-to-S converted waves

These files contain picked arrival times and file descriptions for the P-to-S conversions as described in Daly et al., Illuminating structural variability of the East Aleutian plate interface from local and teleseismic P-to-S converted waves, J. Geophys. Res., 2025. The observations are travel times for local earthquakes to local stations where mode-converted secondary arrivals were observed, explained as P-to-S (PS) conversions. Those conversions appear as strong S-polarized arrivals between the P and S phases, for earthquakes generally more than 40 km deep and paths of several tens to a couple hundred kilometers. The conversions take place near the top of the subducting Pacific Plate, so form evidence for plate structure and geometry. That publication documents the methodology and results; these data are used to make Figures 3, 4, 7, 8 and 11. Earthquake locations are from the "AACSE" dataset described in Ruppert et al. (2023), and station locations match those in the Supplemental Tables of the published paper.
