COVFFT EXAMPLE

UNIX batch job for computing covariance functions and power spectra
from gravity anomalies by FFT:

  covfft <<!
  grav.grd
  covfft.ou1
  covfft.ou2
  79.6 -25 12 18 1
  !

The batch job reads a grid of gravity anomalies <grav.grd> and 
calculates power spectrum, 1-D covariance function and degree variances
(output to <covfft.ou1>) and a 2-D covariance function grid (output to
<covfft.ou2>). Other quantities are written to the screen output.
