Figure 5
Electron-density map of the unit cell for an organometallic example described in the text. Columns from left to right: the reference structure (blue), the ab initio solution by charge flipping using the threshold parameter [\delta = 1.0 \sigma] (red), the final state after one step of the clean-up procedure using the parameter [\delta = 1.5 \sigma] (also red). Top and bottom rows are isosurface plots with levels [1.0 \sigma] and [0.2 \sigma]. In all cases, heavy atoms can be identified already above the level of one standard deviation. Light atoms appear only after the clean-up procedure and only at the [0.2 \sigma] level.
