On the EZNEC main window, Utilities > Ground Info can be used to show the
"frequency adjusted" ground parameters.  I set the "Ground Description" to
(0.004, 13) then used that utility to show the characteristics at 1.0 MHz
and 28.5 MHz.

Here is a composite image comparing the K6STI table to the EZNEC results:

Brian, can you comment on how your table values relate to the frequency
adjusted ground characteristics shown by EZNEC?  I'm afraid the details of
the relationship are over my head.
