Best-fit SED (black) and residuals for COS-DR3-195616 (left panel) and COS-DR1-209435 (right panel), estimated by CIGALE from the UV-to-radio catalogs. Also shown is the unattenuated stellar (blue), dust (red), AGN (cyan), and radio synchrotron nonthermal (orange) emission. Observations are shown by purple circles, with downward arrows indicating upper limits. Estimates of physical properties are shown in the last column of Tables 2 and 3. There appears to be a significant AGN contribution in the case of both UMGs (see Section 5.1).
