1. Examples of the different position of the centre of head rotation (CR).
Examples of the different position of the centre of head rotation (CR). The elliptical cylinder represents the snout (see Fig. 1) and the white circle indicates the middle of the volume. The arrows indicate different lengths of b, which is the perpendicular distance between the middle of the snout volume and the vertical line through the CR. The four discrete positions of b are in clockwise direction b, 0.75b, 0.5b and 0.25b.
