The intensity of the scattering is parametrized as a set of cube-like objects located at the centers of reciprocal space unit cells, resembling very broad and cubic-shaped (1/2,1/2,1/2)-satellites. BMT belongs to perovskites of formula AB$'_{1/3}$B$\"_{2/3}$O$_{3}$ (A=Mg, B$'=$Ta, B$\"=$Mg). The cubes of the intensity can be attributed to the partial correlations of the occupancies of the B site.
