Same as Fig. 8 but also showing results when considering different observed magnitude combinations at z = 0.3. Note for all results shown, we also use all available spectral indices, at z = 0.3, with S/N = 10. The turquoise lines show results for observed optical (these consist of HSC g, r, i, z, and y filters) and IR magnitudes (VISTA H, J, and Ks). The dark orange lines show results for observed optical, IR, and CFHT u^⋆ magnitudes.
