Top: MIRI-MRS for a spaxel within the black region in middle and right panels of Fig. 1. While green crosses represent the regions where continuum emission is extracted, the red-dashed and gray-dashed lines correspond to the best-fit function for such points and the continuum subtraction applied to the spectrum, respectively. Bottom:Spitzer IRS spectrum taken from regions A and B in Fig. 1 and included originally in Beirão et al. (2008). Conventions are as in top panel.
