Illustrative construction of a 3D reciprocal cell using a simulated diffraction pattern with HOLZ reflections. (a) Simulated [211] zone-axis diffraction pattern with ZOLZ and HOLZ reflections for the monoclinic crystal La2(Ti2O7) (listed in Table 1[link]). The red circle marks the HOLZ ring and the open yellow dots are generated by repeating the FOLZ reflections and then superimposed onto the ZOLZ layer. A typical FOLZ reflection, H, is shifted by integral multiples of the basic vectors of OA and OB to the position C1. (b) Enlarged ZOLZ pattern shows 2D geometrical relationship between the basic vectors OA and OB, and the spot C1 (shifted from H), together with the perpendicular intersection points A1 and B1.
