Photometric points of ADF22.A2 and the best-fit SED by MAGPHYS. Filled triangles show the upper limits. For comparison purposes, we also show averaged SEDs for UDS SMGs at z_phot >  3, which are scaled at 1.1 mm and assumed to be at z = 3.991 (Dudzevičiūtė et al. 2020). The faint nature at the K-band and shorter wavelengths can also likely be explained with the z >  3 template, while the limited number of available photometries causes some uncertainties for derived parameters.
