Comparison of the summed SED fits of Figures 11 (top) and 12 (bottom) to the SED of the IRAS16399−0937 system obtained from large aperture (7'') photometry (inverted triangles) and IRS SL and LL spectroscopy (dashed line). The summed small aperture (2farcs02) fluxes of the IRAS16399N and IRAS16399S nuclei are also plotted for wavelengths <14μm, where the nuclei are resolved (filled points and solid line). The top panel shows the sum of the SED models fitted to the IRAS16399N and IRAS16399S nuclei, for the case in which an AGN torus is included in the fit to the IRAS16399N nucleus. The bottom panel shows the summed SED fit for the case in which both IRAS16399N and IRAS16399S nuclei were fitted using only stellar and ISM components. Note that the sum of the SED models does not exceed the upper limits imposed by the large aperture measurements.
