Distribution of the residuals between the measured ALMA flux densities and the flux densities inferred from the SEDs at the ALMA wavelengths expressed as a multiple of the error on the ALMA flux density (σ) for the flat prior (red) and the informed Gaussian prior (blue). The informed prior reduces the mean from 3.44σ to 1.83σ, the standard deviation from 12.21σ to 7.95σ, and the skew from 11.50 to 7.97.
