Same as Fig. 1 but towards G13.22-0.06. The overlaid LABOCA contours go from 0.24 Jy beam^-1 (3σ) to 1.44 Jy beam^-1, in steps of 3σ. The field contains several clumps at different kinematic distances, and therefore only the angular scale bar is shown. The green circles in the Spitzer 8 μm image on the right panel indicate the positions and outer radii of the bubbles N10 and N11 from Churchwell et al. (2006; their Table 2).
