Relation between the amplitudes (multiplied by 103 Å) of the fifth- (U5) and first-order (U1) Fourier coefficients of the modulation functions of model A (open circles), model Dr (filled circles) and the model from Aramburu et al. (2006BB1) (diamonds). The soliton model would require all points to lie on a straight line with a slope that defines the soliton density. The solid line is calculated for a soliton density of 0.4 proposed in Aramburu et al. (2006BB1); the dashed line has been obtained by a least-squares fit to the values of model Dr and it represents a soliton density of 0.45. Error bars indicate one standard uncertainty.
