-We've converted these test points into the GFM file format, that expresses them as depth below earth surface. We used the elevation information to express the test points in GFM format. We'll use this GFM test file, to confirm our CTM query script is returning the same CTM results, for both smoothed and unsmoothed modes, as the CTm notebook.

 This shows the format of the GFM cell data, before it is updated with CTM heatRegionID and CTM temps. The elevation data is from the GFM topography surface. The last 9 lines are CTM test points, with known results, used to verify that the script used to populate the heatRegionID and Temp are producing the correct results for the GFM points.
