Here are the explanations for each of the five columns of the CSV file:
- lat: Latitude is a geographic coordinate 
- lon: Longitude is a geographic coordinate 
- depth: Depth from surface of the earth
- Vs_init: the initial shear wave velocity from ray theory and layered-cake inversion below each surface location
- Vs_adj: the adjoint shear wave velocity tomography result from ambient noise differential adjoint tomography
