Differential hydrogen column density derived from X-ray dust scattering for Sector 1 (black) and Sector 2 (blue), compared to 3D optical extinction maps. Left: Values derived by Lallement et al. (2022), displayed in pink. Right: Differential hydrogen column density from Edenhofer et al. (2024) for Sector 1 (in orange) and Sector 2 (in red). A conversion factor of 1.9 × 1021 cm−2 mag−1 between NH and Av was used.
