M₁ distributions as a function of f_CNM for the set of simulations. These distributions are measured along two orthogonal directions: parallel (lighter color) and perpendicular (darker color) to the mean magnetic field. Filled circles indicate the corresponding mean values ⟨M₁⟩, outlined in black. The case-study simulation is highlighted in red, while the remaining simulations are shown in violet. Two simulations have f_CNM = 26%, leading to an overplotting of their respective distributions. The 3C196 field is displayed in blue witH its associated distribution and mean value.
