Notes. Source fluxes from Gordon et al. (2007) are for an effective wavelength of 71.42 μm and have been colour-corrected to the PACScentral wavelength of 70 μm by dividing by the factor 0.961 (cf. Müller et al. 2011) for a Rayleigh-Jeans-tail-type SED. 100 and 160 μm fluxes for these sources are then extrapolated values for this adopted SED. Source flux models are from (a) http://general-tools.cosmos.esa.int/iso/users/expl_lib/ISO/wwwcal/isoprep/cohen/extraps/, (b) http://general-tools.cosmos.esa.int/iso/users/expl_lib/ISO/wwwcal/isoprep/gbpp/.
