Figure 5
Bragg–Brentano (reflection) geometry. Same colour scheme as in Fig. 4[link]. The component magnitude was set as [Z_{l\semi m,0} = \pm 0.2 (2l+1)], or 1/5 of its upper bound from equation (14)[link]. Still we can see some negative intensity in some regions of the (l, m) = (8, 0) (middle) plot, green line, when the (-) sign is used, so an even tighter bound is necessary in this case. (Top) [{\cal S}(Q)] and its modification with the (2,0) component; (middle) with the (8,0) component; (bottom) with the (8,4) component.
