Broadband SED of AzTEC/C159. The best-fit Draine & Li (2007) model is shown with the blue dashed line. A modified blackbody (red line) is used to fit the FIR-to-millimeter data points. The monochromatic flux densities from Herschel PACS/SPIRE and JCMT/AzTEC observations used in the fit are listed as follows: S_100μm< 6.8 mJy, S_160μm< 13.6 mJy, S_250μm= 6.2 ± 1.9 mJy, S_350μm< 10.8 mJy, S_500μm< 20.4 mJy, and S_1.1mm = 3.3 ± 1.3 mJy (Smolčić et al. 2015). We add three more submillimeter/millimeter data points from our observations: S_870μm= 6.9 ± 0.2 mJy (GG18), S_3mm = 220 ± 40μ Jy, and S_7mm < 20μ Jy. The downward-pointing arrows denote upper limits to the corresponding flux densities.
