Left: comparison between the average observed azimuthal scatter profile from Fig. 7 (black) and the scatter in the simulations for the ENZO runs (red), for the total scatter (solid line) and when filtering out the 1% most-luminous cells (dashed curve). The cyan (NR) and magenta (CSF) curves represent the scatter in the ART simulations. Right: same for the CC (red) and NCC (blue) observed profiles, compared to the 1%-filtered ENZO profiles for the morphologically relaxed (red) and disturbed (blue) simulated clusters.
