Normalized SED from Pearson et al. (2013), as defined in Eq. (3), at z = 2 in contrast with the normalized tabulated fluxes at 250, 350 and 500 μm (vertical dotted) of two H-ATLAS sources at z_MMF = 2: one (J144102.9+012805) that fits well to the model and other one (J233138.6−354345), whose points have been slightly displaced in x-axis to get better clarity, that does not fit properly to the model according to our criteria.
