Geometrics Inc. G-882 Cesium Marine Magnetometer Page 33
Roll angles other than 0, 45, and 90 tend to produce signal to noise ratio
patterns that are asymmetrical. This could cause unequal instrument
performance in the reverse and orthogonal directions of a typical survey.
See CSAZ program.
4.3.2 Main Field Inclination and Total Intensity Maps
The maps on the following two pages may be used to determine the inclination
and total intensity of the Earth's magnetic field in the survey area. The inclination
information may be used to properly adjust the sensor position for the best
performance in the intended area of survey. The intensity information may be
used as a check of the system operation, i.e., that the readings appear to be in
the range that is expected for the survey area. This information is also included
in the CSAZ program.
