Representative results of XFEL-XDI experiments. (A) Representative diffraction pattern from a single Prochlorococus cell. S is the scattering vector defined as \(S = {{2\sin \theta } \mathord{\left/ {\vphantom {{2\sin \theta } \lambda }} \right. \kern-\nulldelimiterspace} \lambda }\), where 2θ is the diffraction angle and λ is the X-ray wavelength. (B) The frequency distribution of lengths of long (upper right) and short axes (lower left) of projection electron density maps (upper left) and their correlation (lower right).
