Upper left: CO(7–6) emission integrated over the velocity range [ − 120,60] km s^-1. The black contour levels start at 3 × σ and are spaced by σ = 135 mJy beam^-1 km s^-1. The white ellipse at the bottom right represents the beam at half maximum (0.71′′ × 0.28′′). The HST map contours are overlaid in cyan. Upper right: the 212 GHz continuum map. The black contour levels start at 3 × σ and are spaced by σ = 0.28 mJy beam^-1. Lower left: the CO(7–6) integrated spectrum with the best Gaussian fit overlaid. Lower right: best-fit modified black body spectral energy distribution to the FIR continuum measurements derived by Wu et al. (2009), Barvainis & Ivison (2002), and us (red dot at λ = 1.41 mm).
