(a) position error of 5° transversal rotation recordings calibrated with 0° calibration, (b) position error of 5° longitudinal rotation recordings calibrated with 0° calibration, (c) distortion error of 5° transversal rotation recordings calibrated with 0° calibration and (d) distortion error of 5° longitudinal rotation recordings calibrated with 0° calibration. All errors are given with two standard deviations.
