Caption: Figure 17.

Color-coded maps show the best-fit Ar (dust extinction along the line of sight) per pixel for the SDSS-SEGUE strip centered on l = 110° (modeled after Figure 25 from M. Berry et al. 2012). Each pixel, defined in Galactic coordinates, shows the median Ar according to the legend below each panel. The three panels correspond to distance slices of 0.3–1 kpc (left), 1–1.5 kpc (middle), and 2–2.5 kpc (right). Note that the median extinction increases rapidly with distance. In the right panel, there are no stars in the white regions in the center because extinction makes them fainter than the sample magnitude limit.
