Projection of sources onto the self-organising map (SOM) trained using 8-band photometric data (DES g, r, i, z bands and EuclidI_EY_E, J_E, and H_E bands). Each SOM cell consists of objects with similar spectral energy distributions (SEDs). The background grayscale indicates the number of objects mapped to each cell. The red dot marks the true flux of a selected object projected onto the SOM, while the blue and green markers show 50 independent realisations of the same object with Deep and Wide photometric noise, respectively.
