 +(1*) Specifications are subject to change. Assumes the TCM is motionless and the local magnetic field is clean relative to the 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.
