Figure 5: Two-dimensional structure.
From: Two-dimensional structure from random multiparticle X-ray scattering images using cross-correlations
(a) Averaged 2D electron density ρ from 50 reconstructions. ρ is normalized to be on average unity in the core of the structure. One real-space pixel corresponds to 13.0 nm, and the red bar corresponds to 100 nm. The dashed white rectangle delimits the region of compact support imposed during the iterative phase retrieval procedure. The two dashed magenta lines are the ρ=0.9 and ρ=0.1 contour levels, and their average separation provides an estimate of the achieved resolution of 17.5 nm. (b) Phase-retrieval transfer function PRTF(q) resulting from the 50 reconstructions, as a function of q. The red dashed vertical line marks the q value corresponding to the resolution estimated in a. (c) Horizontal section (h–h′) and vertical section (v–v′) through the 2D electron density ρ, at the positions marked in cyan in a.
