Input information for AMPLIMODES for FullProf: high-symmetry phase information (virtual prototype structure), low-symmetry structure information (cell parameters obtained by XRPD data refinement) and transformation matrix. R \overline{3} (No. 148, standard setting) and F m \overline{3} m (No. 225, standard setting). (Information for the monoclinic \left(P 2_{1} / n\right) case is in [1].)
