Footnotes:
1. Specifications are subject to change. Assumes the TCM is motionless and the local magnetic
field is clean relative to the user calibration.
2. For example, if the calibration was performed over ±10° of tilt, then the TCM would provide <2°
rms accuracy over ±20° of tilt.
3. Performance at maximum operational dip angle will be somewhat degraded.
