The accompanying ACCESS.MDB file contains airborne geophysical data. Locations are given as both UTM NAD 27 and WGS 84 Lat-Longs. Column headings clearly define the various fields. 

Geophysical products are consistent with the DIGHEM V system and include computed resistivities, in-phase and out-of-phase components, and depth estimates for a number of frequencies. These products are summarized in the following table.
