Seismic first breaks for Syczyn seismic survey

The dataset contains condensed results of seismic refraction survey, that can be regarded as “hard data”. Data files Syczyn-1_P.ASC and Syczyn-1_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively; Data files Syczyn-2_P.ASC and Syczyn-2_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively. Each file contains 4 columns: Record No. – sequential record identifier; Source location – distance from the beginning of the line to the (current) source point (in meters); Receiver location – distance from the beginning of the line to the given receiver (in meters); First Break – delay time between emission of the wave to its arrival at the given receiver point (seconds). Dataset is formatted in simple table, that can be imported to other seismic software for modelling velocity field. Different computing algorithms generate slightly different velocity models, so it can be useful to have hard data for comparison.

本数据集汇聚了地震折射调查的浓缩结果，可视为‘硬数据’。数据文件Syczyn-1_P.ASC与Syczyn-1_S.ASC分别代表沿Syczyn-1线获得的P波和S波表格；数据文件Syczyn-2_P.ASC与Syczyn-2_S.ASC分别代表沿Syczyn-1线获得的P波和S波表格。每份文件包含四列：记录编号——顺序记录标识符；震源位置——自线路起始点到（当前）震源点的距离（米）；接收器位置——自线路起始点到指定接收器的距离（米）；首次波到达时间——波发射至到达指定接收点的时间延迟（秒）。数据集以简单的表格格式呈现，可导入其他地震软件进行速度场建模。不同的计算算法会产生略有差异的速度模型，因此拥有硬数据以供比较颇具价值。
