I figured I'd post a quick video of the model reflected in my abstract. You can find the link HERE.
Turns out, I had misinterpreted my results in the last post. So take the opposite of everything I said there. The trend in velocities appears to be NE to SW across the whole array, with slower velocities in Missouri, transitioning to faster velocities in Kentucky. As you watch the slice progress through the model, note the transition in the upper quarter or the model from red to green to blue. The slice is angled appropriately to represent the apparent location of the transition zone (about parallel to the Ohio River).
As for the deep sections of red and blue, or the sections outside the red dots (which are our stations), these are tomography artifacts and are to be ignored. Additionally, since my model doesn't have a crustal or basin correction, the results we can see in the bounds of our coverage may not even be correct. But hey, it's a step in the right direction!
