Spectral energy distribution of our SMGs. Red diamonds present the PACS and SPIRE measurements, while green squares present multi-wavelength ancillary data taken from the literature. The modified blackbody emission (β = 1.5) best-fitting the data are shown by dashed blue lines. The power-law temperature distribution model (β = 2.0, γ = 7.3 and R = 3   kpc) which best-fits the data are shown by solid red lines. Dotted lines present the CE01 SED template which best-fits the far-infrared observations.
