Comparison between pixelized star polarization angle maps for stars within 400 pc (left) and stars beyond 1.2 kpc (right). Each yellow line segment traces the mean polarization angle of stars in a given pixel. The polarization angles of pixels toward the TMC (white segments) are excluded from the analysis. The Galactic plane is marked with a white horizontal dashed line. The background image shows the cumulative extinction out to 400 pc from Edenhofer et al. (2024) (as in Fig. 3).
