Notes. Uncertainties correspond to the 1σ level, and upper limits are quoted for 3σ. Integrated flux values are derived from fitting point sources at the positions of images A and B in the CO(1–0) and CO(3–2) maps collapsed for velocities between  − 350 and  + 170 km   s-1, as described in the text. This velocity range was determined from the spectral extent of the CO(3–2) spectrum. Measuring the fluxes in the individual and combined spectra yields results within 10% of those reported here.
