(Top) 2D section through the physical space electron density map perpendicular to the tenfold direction. The RPT (gray) and PPT (orange) are plotted over the contour plot. Hiraga clusters (black) are centered at the vertices of the PPT. (Bottom) HRTEM image of the decagonite structure with both RPT and PPT plotted over the image for guidance. Plotted tiling are τ times deflated in comparison with tilings in top contour plots. The isosurfaces of the electron density are compared with the magnified patch of the HRTEM image further supporting the agreement between the obtained ab initio structure solution and the real-space structure. The positions of clusters that are not centered in the PPT are located in the positions of the rearranged tiling: these are phason-flip-equivalent positions.
