(a) Results from the conventional symmetry adapted modes' amplitude refinements. See the text for details. (b) The structures obtained after having passed to AMPLIMODES, after applying the origin shift proposed by the program. The anomalous evolution of the $\mathrm{Na} / \mathrm{K}$ amplitude, in the whole temperature range, is even more evident.
