A refinement was carried out in TOPAS Academic using both this and the flat plate data sets simultaneously. The preferred orientation was modelled according to March (1932) using the Preferred_Orientation(@, 0.89877`,, 1 1 1) macro in TOPAS Academic. The preferred orientation was found to be in the (111) direction with a March parameter of 0.89877. ; _pd_proc_ls_profile_function ; Simple_Axial_Model(7.28762) function with Rp=9999,Rs=300 in TOPAS-Academic ; _pd_proc_wavelength 0.6967 _pd_spec_mounting ; flat plate ; _pd_spec_mount_mode reflection _pd_spec_shape flat_sheet _pd_spec_size_axial 8 _pd_spec_size_equat 27 _pd_spec_size_thick 0.5 _refine_ls_goodness_of_fit_all 1.347 _refine_ls_number_parameters 58 _refine_ls_weighting_details 1/(sigma*sigma) _refine_ls_weighting_scheme sigma _cod_data_source_file ja0770983-file005.cif _cod_data_source_block Pb2S4C8N2H2 _cod_original_cell_volume 330.3227 _cod_original_formula_sum 'Pb S2 C4 N H5' _cod_database_code 4107279 _cod_database_fobs_code 4107279 loop_ _symmetry_equiv_pos_as_xyz '-x, -y, -z' 'x, y, z' loop_ _atom_site_label _atom_site_type_symbol _atom_site_symmetry_multiplicity _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_occupancy _atom_site_B_iso_or_equiv Pb1 Pb 2 2.302535 -2.953475 -19.65324 1 0.8613958 S1 S 2 -0.2316663 -0.2088174 0.3413686 1 0.8613958 S2 S 2 -0.1803035 0.1957249 0.4053059 1 0.8613958 C1 C 2 -0.1049087 -0.09456174 0.1545868 1 0.8613958 C2 C 2 -0.08164938 0.08863288 0.1835404 1 0.8613958 C3 C 2 0.02325934 0.1831946 0.0289536 1 0.8613958 C4 C 2 0.4584822 0.415469 0.03061807 1 0.8613958 N1 N 2 0.3466771 0.4314337 0.2480671 1 0.8613958 H1 H 2 0.03960525 0.3119378 0.04930125 1 0.8613958 H2 H 2 0.4576634 0.4329294 0.2983064 1 0.8613958 H3 H 2 0.2245016 0.5698967 0.2962646 1 0.8613958 H4 H 2 0.5806577 0.277006 -0.01757945 1 0.8613958 H5 H 2 0.3472586 0.4435613 -0.02780249 1 0.8613958
