This example of multiple station scalar measurements further defines the use of the station
identifier for the E-fields in the Sta/Ant field. The notation used here is as follows: RHOxy
2
means the Cagniard resistivity is calculated using Ex
2
(channel 3) and the Hy from the next
nearest channel (channel 4, which we label Hy
2
). Likewise for the phase difference calculations,
the phase for Ex
2
(channel 3) and Hy
2
(channel 4) are used to form the difference.
For this example we are using four single channel ANT/1's for the H-field measurements.
