Background-subtracted and bias-corrected FIR SEDs, before and after decomposition in SF and QG components: total signal (purple), SF satellites (grey), and QG with error bars on the side (light pink). Only the point-source component of the QG SED is shown (that is, after subtraction of the autocorrelation term). As described in Sect. 3, the satellite points are fitted to the data at ≤160 μm and extrapolated from Magdis et al. (2012) templates at longer wavelengths.
