Upper left: column density map of NGC 6611 with radial segments as indicated. Upper-middle to lower-right: dust temperature (black) and column density (red) PA-averaged radial profiles in each segment. Segments are arranged clockwise starting with the Pillars of Creation (upper-middle) to the cavity region (lower-right) as identified by numbers. The profiles are the median values with projected distance in each segment to avoid biases by the presence of protostars. The radial lengths of each segment were defined by a drop in column density (as seen in the upper-left panel).
