Maps of the reddening caused between 0 and 500 pc (top), and 500 and 1000 pc (bottom), calculated by integrating profiles from Fig. 9 over the selected distance range. The pixel size is set by the resolution of the Green et al. (2015) model. The top plot shows the presence of a field-filling dust cloud (assumed to be a neutral region) while the bottom shows the presence of a more distant cloud that occupies only part of the field.
