Fig 5. Spatially uncorrelated position disorder in hexagonal RGC mosaics induce broadband noise in iso-orientation domain layouts.

A Numerically calculated orientation domain layouts with disorder strength η = 0.12. From left to right: Moiré interference pattern, filtered Moiré interference pattern (OSI > 0.25), smooth layout and the smoothed layout’s amplitude spectrum. Insets show magnified regions. Circles in the amplitude spectrum mark k _c (red) and $\sqrt{3}{k}_c$ (blue) (cf. Eq (6)). B As A but for a higher disorder strength η = 0.30. C Radially averaged normalized amplitude spectra of the orientation domain layouts for different disorder strengths. The fluctuation strength is color coded (legend). x-axis is given in units of k _c (cf. Eq (6)). D As C but for the smoothed layouts. All other model parameters as in Fig 3.
