If you select D-station-interpolation, station numbers are linearly interpolated as follows:
0075N 001937.0E 060326.34
0075N 001937.3E 060326.72
0075N 001937.5E 060326.92
Column 1: Line number and direction
Column 2: Interpolated Station number and direction
Column 3: Uncorrected magnetic field (nT)
NOTES:
The station number always has an extra digit added to the end for the
interpolation. If you are planning to use station interpolation for walk files, keep
in mind the number of readings and the distance between pickets by managing the
cycling time and the station increment. If you have too many readings and small
station increments, some interpolated stations have repeated values.
B.5 GRADIOMETER OPTION
Data obtained with the gradiometer option is sent as follows.

Column 1: Time, as hhmmss.s
Column 2: Line number and direction
Column 3: Station number and direction
Column 4: Unreduced magnetic field
Column 5: Magnetic field gradient (nT/m) and sign
Column 6: Reduced magnetic field (nT)
