Top panels: Spitzer 24 μm map (color scale), and PdBI 1.3 mm emission intensity map with the PdBI 1.3 mm primary beam indicated as dashed circle. The contour levels start at  −3σ, 3σ in steps of 5σ. Center panels: Spitzer 24 μm map (color scale), and PdBI NH₂D peak intensity map. The NH₂D contour levels start at  −3σ, 3σ in steps of 2σ. Bottom panels: the NH₂D spectra towards the brightest position for the respective sources in the top panel. The brightest NH₂D peak is is clearly offset from the Spitzer point source and brightest mm core in both cases, and that the clumps are detected at high S/N through out the map.
