Sand Dunes Earthquake Locations - hypoDD using Rio Grande Rift velocity model is preferred

From the publication "Earthquake swarm near Great Sand Dunes, Colorado, investigated with temporary seismic network and machine learning seismic phase analysis." in the Mountain Geologist. Three catalogs were produced using different location algorithms. The catalog titled hypoDD_RGR is the preferred catalog. There were 717 events located by glass3 and SEISAN. 700 of those events were located by hypoDD. Column hypoDD_ID reconciles the events in all three catalogs.本数据集源自发表于《Mountain Geologist》的学术论文《科罗拉多大沙丘附近地震群：临时地震台网与机器学习（machine learning）震相分析研究》（Earthquake swarm near Great Sand Dunes, Colorado, investigated with temporary seismic network and machine learning seismic phase analysis）。研究采用不同定位算法生成了三份地震目录，其中命名为hypoDD_RGR的目录为推荐首选目录。通过glass3与SEISAN软件共定位得到717个地震事件，其中700个事件经hypoDD完成定位。hypoDD_ID列用于匹配整合三份目录中的全部地震事件。
