In the left-hand panel the 250 μm image is shown, together with the 5 apertures where fluxes were measured. The total aperture corresponds to the outermost elliptical aperture. The best fit values and uncertainties are given in Table 1. In the right-hand panel we show the fit to the observed SEDs as measured in the four apertures: observed fluxes (triangles) are superimposed to the modified black body curve (lines), corresponding to the best fit values of the temperature. Different colours and lines correspond to different apertures/annuli.
