Side-by-side comparison of the ratio of the simulated and observed SEFD_U/SEFD_I at gridpoint 114. (a) Simulated image of SEFD_U/SEFD_I with the corresponding contour levels. (b) Observed SEFD_U/SEFD_I with the corresponding contour levels (black curves) and the contour levels of the simulated values (white curves). The observed image has a size of 4096 × 4096 pixels and was smoothed using a Gaussian filter of size 201 × 201 to smooth the noisy image.
