Top left panel: surface brightness profiles, Σ_IR, for PACS, MIPS, SPIRE, and IRAC 3.6 μm. Top right panel: radial temperature trends T_dust and emissivity index trends β vs. normalized radii, R/R_opt. Sets of fluxes are defined over ≥4 wavelengths. The bottom panels show each individual SED fit, Σ_IR vs. wavelength, with best-fit temperature and emissivity index β. The DL07 best-fit models are shown as a (blue) dashed line, and the MBBV fits as a (red) solid one. S/N lower limit = 3.0. The 70 μm (PACS+MIPS) and 500 μm points are excluded from the fits.
