BUCKDC_TXT Subdirectory

The following are ascii text files for dc resistivity sounding data and
interpretation. The sounding numbering system follows that given in the open-
file. 

Units are in meters for separations and layer thicknesses. Units are in ohm
meters for resistivity.

Files *.img are interpreted subsurface resistivities for the given layer
structure.

Files *.rpd contain the sounding data consisting of separation and measured
apparent resistivity.
