A Keller-Segel model for C elegans L1 aggregation

Spectral comparison of experimental and simulation results.
A. Last frame of aggregation video S1 Video, cropped to a square to facilitate Fourier analysis. This square is 1.93 cm in size. B. Final time point of the full-scale simulation Fig 6, cropped and scaled to match A as closely as possible, with a corresponding central mass added. C. The central mass alone. D. Low-frequency region of the two-dimensional power spectrum of the discrete Fourier transform of image A. The power scale is truncated at 10 AU (arbitrary units) E. Low-frequency region of the power spectrum of image B. The power scale is truncated at 20 AU. F. Radially summed power spectra of images A,B, and C. Peaks of the experimental image spectrum are picked out in blue.
