Supplementary Figure 8: BEV2 phase extension of XFEL data.

(a) Stereo diagram of a 5-fold real space averaged electron density map at 5 Å resolution prior to phase extension. (b) Electron density map after phase extension to 2.5 Å by cyclic real space averaging and solvent flattening. (c) Scatter plot of phases derived from XFEL data via phase extension and those derived from an averaged map calculated from synchrotron data. Phases are only shown for reflections in the resolution range 5 Å to 2.5 Å.
