Pn travel-time data and inversion results in the southwestern United States

Table 1: The Pn travel-time data used for tomographic inversion in the southwestern United States. "slat", "slon", "mag", and "sdepth" represent the latitude, longitude, magnitude, and hypocenter depth, respectively; "yr", "mo", and "da" indicate the origin time (year, month, day); "name", "rlat", "rlon", and "elev" denote the station code, latitude, longitude, and elevation, respectively; and "ttime" represents the Pn travel time. Table 2: Measurements of Pn velocity and anisotropy in the southwestern United States. The five numbers in each line are the longitude, latitude, Pn velocity, magnitude of Pn anisotropy, and direction of the fastest wave propagation (rotate counterclockwise from east) at each grid.表1：用于美国西南部地区层析反演的Pn波走时数据集。其中“slat”、“slon”、“mag”及“sdepth”分别代表震源纬度、震源经度、震级与震源深度；“yr”、“mo”、“da”依次表示发震时刻的年、月、日；“name”、“rlat”、“rlon”与“elev”分别代表台站代码、台站纬度、台站经度与海拔高程；“ttime”则表示Pn波走时。表2：美国西南部地区Pn波速度与各向异性测量结果。每行包含的五个数值分别为各网格点的经度、纬度、Pn波速度、Pn波各向异性强度以及最快波传播方向（以正东方向为基准逆时针旋转得到的角度）。
