Dataset S6

Raw velocity seismograms for SKS phases propagated through the simplified hexagonally anisotropic subduction zone model. Seismograms are in SAC format (see SAC manual; http://ds.iris.edu/files/sac-manual/). The TauP predicted SKS arrival time through IASP91 is stored for reference. SAC files are written individually for each station and component for a particular event. The filenames follow the format EVT.STN.X where 'EVT' is a unique numeric event ID (see Dataset S2), 'STN' is the station name (see Dataset S1), and 'X' is 'N', 'E', or 'Z' corresponding to the north, east, or vertical seismogram component.
