Influence of the number of SOM clusters on the resulting tomographic bin redshifts and the recovered photometric misrepresentation for the full KV450 photometric and spectroscopic datasets. The figure is constructed in the same way as Fig. B.1. Here we additionally show the point at which the tomographic bin mean redshifts cross the |⟨z⟩_n − ⟨z⟩_max| ≤ 0.01 boundary (shown with grey shading). This criteria designates our per-tomographic-bin cluster-number choice for this work.
