Dendrogram of G305 on ¹³CO spectral cube. The structures that show greater than ~67% overlap with the 8 μm mask (regions with 8 μm flux greater than 100 MJy sr⁻¹ representing molecular gas influenced by feedback from the central star clusters in G305) are colored red; those with partial overlap (between 10–67%) are colored green; and the structures with less than 10% overlap with the 8 μm mask are colored blue.
