Rotation measure scatter profiles (𝔖_RM). The color-shaded regions represent the 68% C.L. error regions for the MiRò profiles (made with a sliding window of fixed size 0.01 r₅₀₀). We show the five MiRò models with highest Bayesian evidence. The black line represents the observed scatter profile and the gray shaded region represents its 68% C.L. error region. The vertical line is at 0.7 r₅₀₀, where overlapping structures start to dominate.
