Dataset S4

Raw velocity seismograms for direct P and S phases propagated through the isotropic subduction zone model. Seismograms are in SAC format (see SAC manual; http://ds.iris.edu/files/sac-manual/). Arrival times for P determined via waveform cross-correlation are stored in the appropriate SAC header. The TauP predicted S arrival time through IASP91 is also 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.

本数据集包含通过各向同性俯冲带模型传播的直达P波与S波原始速度地震图。地震图采用SAC格式（详见SAC使用手册；http://ds.iris.edu/files/sac-manual/）。通过波形互相关算法测定的P波初至时间已存储至对应SAC文件头中。通过IASP91地球模型由TauP程序预测得到的S波初至时间也已存储以供参考。每个事件的SAC文件均按台站与分量分别存储。文件名遵循EVT.STN.X的格式规则：其中"EVT"为唯一数值型事件ID（详见数据集S2），"STN"为台站名称（详见数据集S1），"X"为"N"、"E"或"Z"，分别对应北分量、东分量与垂直分量地震图。
