Calibration rotations through 360° about each of the TriMag axes (cf. Fig. 4), as visualised on the m-sphere. In this trial, multiple rotations were undertaken about each axis and are shown by lines of points in the circles created, coloured by each axis (blue = yaw, red = roll, dark grey = pitch). Variation in the position of points within a single rotational ring, are due to wobble in the rotating arm on which the tag was mounted
