Distribution of the angular differences Δθ = θ_stellar − θ_RHT. The histogram shows the observed frequency of angle offsets between the stellar polarization and the RHT-derived orientations. The red solid line represents the best-fitting skew-t distribution, which provides an excellent description of the asymmetric shape and extended tails of the data. The distribution is strongly peaked near zero, indicating a high degree of alignment between the two tracers, with a slight skewness reflecting residual systematic deviations.
