Predicted vs true values, for the sample of 4333 galaxies (H-ATLAS + DustPedia). The predictions are derived from Bayesian SED modelling to the UV–MIR broadband fluxes. The ground truth values are also derived from a Bayesian SED fit, but instead make use of the full UV–FIR broadband fluxes. The error bars are derived from the likelihood-weighted standard deviations reported by the CIGALE fits. The colour of the points reflects a 2D kernel density estimate, with brighter colours corresponding to denser regions. Top two rows: log-normalised fluxes (F_3.4 μm is the Bayesian estimate of the WISE 3.4 μm band from the UV–MIR SED fit). Bottom row: intrinsic dust properties. Each panel lists the RMSE and ME (ME = ). For the dust luminosity and dust mass, these are calculated in log-space (dex), but for the dust temperature they are not.
