Figure 5
I_z(B_x, B_y) projections of the reciprocal-space maps of 102, 002, 222 and 013 reflections from a BaTiO₃ crystal containing a ferroelastic domain of tetragonal symmetry. The white lines correspond to the equation $[({B_x^2 + B_y^2 + B_z^2} )^{1/2} = | {{\bf B}_{\rm calc}} |]$ [here |B_calc| was calculated using tetragonal lattice parameters a = 3.962 (1), c = 4.005 (2) Å].
