The dust temperature (top) and column density (bottom) profiles along the Eastern (left) and Northern (right) Filaments. The positions along the filaments are plotted as a function of their projected distance from the cluster. The NGC 6611 cluster is located at “0” on the x-axis, centred at 18 18.8  − 13 49. The green dashed line on the dust temperature (top) is the dust temperature after removing the effects of cold sources within the filaments, following the relation of Juvela & Ysard (2011; Fig. 1, see footnote 6 and also Didelon et al., in prep., who examine this relation for Herschel filaments). The thick vertical lines seen on the profile of the Northern Filament indicates structures at the same distance from the cluster, as the filament tends to curve around the cavity.
