This may seem like a lot of images, but I'm trying to keep consistant with past deliverables and provide an image of each interim product to explain comments made in the error analysis.  In this deliverable I work to refine some lessons learned on the Kingman and the approach required lots of interim products.

I've provided grids that integrate the data from all three images in two different ways. One more statistically accurate and one more visually pleasing.

I also take a bit of a new approach in my error analysis.

Always working to improve ...
