MAGNETIC DATA PROCESSING DETAILS
--------------------------------

The final magnetic data provided has been corrected and levelled using the following processes:
  * The diurnal magnetic base station data was applied to the survey data for removal of diurnal variations.
  * The regional magnetic gradient (IGRF) computed at the date of the survey was removed from the survey data.
  * System positional parallax was corrected.
  * The data was levelled using the survey tie line data.
  * The data was microlevelled to remove minor residual variations in profile intensities.


GRIDDED DATASET FORMATS
-----------------------

Gridding was performed using a bicubic spline algorithm.  The following grid formats have been provided:
  * ERMapper format
  * Geosoft 2 byte integer format
