SMA continuum at 1.3 mm (contours) overlaid with SCUBA 850 µm density flux from Nutter et al. (2005). The contours start at 5σ and continue in steps of 5σ (σ = 18 mJy beam⁻¹). The empty circle indicates the size of the SMA primary beam, whereas the SMA synthesised beam is shown with a white ellipse in the bottom left corner. The empty rectangle shows the map covered by APEX observations. The stars mark the position of the objects located in the Coronet cluster; refer to Table 1 for their identification.
