5.1.2 2D Calibration
A 2D Calibration is intended for very low tilt operation (<5°) where calibrating the TCM
with greater tilt is not practical.
This procedure calibrates for hard and soft iron effects in only two dimensions, and in
general is effective for operation and calibration in the tilt range of -5° to +5°. The
recommended 12 point calibration pattern is a circle of evenly spaced points, as given in
Table 5-3.
