An example of a GRADIENT array setup:
The AB transmitter dipole is set up on grid line 52,000 N, a-spacing = 50 m, the north-south
baseline runs through the middle of the array, so that A is at -350 meters (350 W) and B is at
+350 meters (350 E). The first potential electrode as shown is located at -100 meters (100 W),
and 100 meters north of the transmitter dipole, or 52100. The data would be input as follows:
