Left: fitted reddening E(B − V) against distance for all fitted stars. As a comparison, linear extinctions of 0.7 mag/kpc (red) and 1 mag/kpc in the V-band as used in the Besançon model and in Dressing & Charbonneau (2013), respectively, are overplotted as dashed lines. Right: average fitted E(B − V) in relation to the coordinates (J2000). One can see the dust-rich region in the upper right which is closer to the galactic disc.
