Example SED for a core with the median properties of the “near” sample: M = 2   M_⊙ and T = 20 K. The solid black curve depicts the SED assuming optically thin emission over the full spectrum. The cyan dashed curve shows an SED with the same parameters, but without an assumption of optically thin emission. The blue, green, and red dash-dotted curves show the filter response function (× 10^-3) for the 70 μm, 100 μm, and 160 μm bands, respectively. The full range of fluxes at each wavelength for 24 μm-bright (red dotted line) and 24 μm-dark (gray dotted line) are shown. All flux densities have been normalized to the fiducial 4 kpc distance.
