Polar view of the sample of stars (marked as points) with color-coded quantities: R_P/p, P_S, p_v, and distance. The units of R_P/p and P_S are MJy sr⁻¹. The degree of polarization, p_v, is measured in percentage (%) and the distance in parsec. The northern hemisphere is shown in the top row and the southern in the bottom row. For R_P/p, only stars with P_S/σ_PS ≥ 2 are shown, and in the other maps all measurements are displayed. Several large-scale structures can be identified because they present high polarization, p_v and P_S. Figure created with TOPCAT (Taylor et al. 2005).
