2 BE = Barometric elevation; AG = above ground, in ft.

3 Years next to IGRF and DGRF indicate the year of the model used, updated to the time of the survey. Two years shown next to DGRF indicate a linear interpolation between the coefficients of those two models. POGO (Polar Orbiting Geophysical Observatory) model followed by month and year of the model. The POGO model listed was provided to the survey processors by J.C. Cain (Florida State University) but was never published.

4 NURE = National Uranium Resource Evaluation program.
