Dust SED modeling for the central beam (the hot DOG). Left: Observed continua flux (purple points) as a function of rest-frame wavelength, and fitted modified blackbody (green line). The best-fit parameters and reduced χ² of the fit are indicated in the plot, and the residuals of the fit are shown in the bottom panel. Right: Corner plot showing the marginalized 1D and 2D posterior probability distributions for the parameters used to fit the modified blackbody. The green solid lines show the position of the best-fit values, and the dashed lines indicate the 68% confidence interval. The high dust temperature suggests that the quasar is likely the primary source of heating.
