Fobs Fourier maps of the (3+1)D superspace around selected atoms, projected on the x2–x4 planes. Horizontal axes display x2 fractional coordinates (y coordinates) and vertical axes correspond to x4; the contours are in arbitrary units and, in kinematic approximation, represent the intensity of the electrostatic potential. The fitted atomic modulation functions, represented as continuous white lines, show how the modulation causes the atoms to displace from their average special position on the mirror plane, represented as a dashed yellow line.
