Distance determination for the Pipe Nebula, Musca, Polaris Flare, and Aquila Rift clouds. Each subpanel shows the differential G-band extinction per parsec as a function of distance for different sightlines within the Herschel map of each cloud (transparent black lines). Old distance estimates (adopted in Arzoumanian et al. 2019) are shown as a vertical dashed line, while the new distance measurement for each line of sight is shown as a red vertical segment at the top of each panel.
