Comparison of the σ _add and m ₂ complexity metrics for polarized components in the median-filtered GL observation. The points are colored by log₁₀(S/N_pol), and the thresholds for complexity for both metrics are shown by dashed lines: σ _add = 1 (blue vertical) and m ₂ = 0.5 (red horizontal). Note that the σ _add axis is on a log scale, while the m ₂ axis is on a linear scale.
