Examples of MBD reflectivity contours computed by DXRD. (a) Reflectivity contour of the primary reflection 004 in 000–004–111–113 4BD with the HRD [100]. The principal azimuthal angle is [{{{\Phi}}_{4{\rm{BD}}}} =] [- 37.94^\circ], where the 4BD condition is fulfilled. [\Delta\Phi=\Phi-\Phi_{\rm 4BD}]. [\Delta\theta=] [\theta-\theta_{\rm B}]. (b) 111 reflectivity contour in 000–111–002 3BD. [{{{\Phi}}_{3{\rm{BD}}}} = 16.58^\circ] from the HRD [[{1\bar 10} ]]. (c) Reflectivity contour of the forbidden primary reflection 002 in 000–002–111 3BD. [{{{\Phi}}_{3{\rm{BD}}}} = - 51.04^\circ] from the HRD [100]. The incident beam is a plane wave with E = 8 keV for (a)–(c). (d) Intensity contour of reflection 002 under the same conditions as in (c) except that the incident beam has an angular divergence of 10 µrad along both the [\theta] and [{\Phi}] directions and a spectral bandwidth of 1 eV. σ Polarization. [{{{\Phi}}_{{\rm{off}}}} = {{{\Omega}}_{{\rm{off}}}} = 0].
