This example is a plot of calibration points and the derived calibration curve for the vehicle PROBE1 (P1). It can be seen that the error in the flux gate compass, primarily caused by the vehicle's magnetic field, is about 12 degrees when the vehicle heading is roughly southwest, and generally less than this amount...
