 Raw CSV data showing each point plotted and the value of those points can be found using the following link.
-Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer.
+Below is a summary of each slice and the minimum and maximum Vp/Vs for each layer. Each layer is 500m deep. So layer 1 is surface (0m), layer 2 is 500m depth, etc.
 NOTE: THE LOWEST AND HIGHEST VALUES BELOW ARE THE LOWEST AND HIGHEST OUTSIDE OF THE BOUNDARIES. SO WHEN IT SAYS LOWEST 1.8, THAT DOESN'T MEAN THE LOWEST RATIO FOUND IN THE ENTIRE LAYER WAS 1.8, IT MEANS THAT THE LOWEST ABNORMAL RATIO FOUND WAS JUST SLIGHTLY ABOVE 1.8 (I.E. THIS LAYER CONTAINS NO VALUES THAT GO BELOW 1.5).

	In order for the CyberShake simulations to be successful and stable, the Vp/Vs ratio needs to be calculated. Too low or too high of a ratio is scientifically inaccurate and can cause instabilities within the wave propagation simulation codes.
