The original contractor data has been edited as follows;

- Tx loop vertices corrected;
  some vertices from one loop were incorrectly included in the other loop
  making it appear to be twice the size it really was.

- Corrected Tx loop vertex heights based on AHD digitised from contour map.

- The AUV component data ("XYZ" in contractor terminology) for Loop 2
  are STILL THE SAME SIGN AS RECORDED BY THE CONTRACTOR.
  See separate note files concerning these signs.

- The edited data was then imported into Maxwell, exported as TEM file format,
  and finally the A ("Z") and UV ("XY") components concatenated into a single
  merged TEM file (one for each Tx loop). These filal files are;
  SJ1_reexport_L1_merge_XYZ.tem
  SJ1_reexport_L2_merge_XYZ.tem
  and allow all components to be loaded into Maxwell software in a way that
  they are treated and displayed as complete lines of 3 component data.
