Qualitative comparison of distance profiles between dust polarization and dust extinction tomography results. Top: profiles of the “differential” of the degree of polarization (δp_C, computed locally from δq_C and δu_C) as a function of distance modulus as inferred from our polarization 3D map. Bottom: differential extinction as a function of distance modulus as inferred from the 3D extinction map of Vergely et al. (2022). No extinction data is available at distance larger than about 1 kpc. The surveyed sky area is sampled according to an HEALPix map with N_side = 128. Each LOS is represented with a different color, the same color is used across panels. The green vertical strip indicates the range of distances to the inner surface of the Local Bubble in this sky area (Pelgrims et al. 2020).
