Far-IR and radio SED of ESO 320-G030. Tables 2 and 3 list the wavelength (or frequency), flux, and instrument of the plotted measurements. The cyan line is the best gray body fit to the far-IR photometry (Sect. 6.1.2), the dashed dark blue line the best power-law fit to the radio (ν ≤ 36 GHz) emission after subtracting the thermal radio continuum (dot-dash green line) to the observed data (Sect. 6.1.1). The solid red line is the sum of the three components (gray body, thermal radio continuum, and synchrotron). The error bars are smaller than the symbols.
