Reconstruction of the 3D electron density. (a) Reconstruction from the result derived by EMC. The electron density projected along an axis perpendicular to the drawing plane is shown here. (b) Reconstruction from the reference Fourier volume. Again, the projected electron density is shown. (c) 3D iso-surface rendering of the reconstructed electron density shown in panel (a). The threshold of the iso-surface has been set to 0.2, given a normalized density with values between 0 and 1 (see also animation in the supporting information). (d) Scanning electron micrograph from the original sample.
