Example of best-fit models (in black line) to the observed spectral energy distributions (SEDs) of two galaxies of our sample. One is a typical late-type galaxy (HCG2a; top panel) and the second is a quiescent elliptical galaxy (HCG62a; bottom panel). In each panel, the blue line shows the unattenuated stellar spectrum estimated by the model. The red circles are the observed broadband luminosities with their errors as vertical bars. The residuals, , are shown at the bottom of each panel. Note the uncertainty in the far-IR shape of the SED due to lack of high spatial resolution data.
