Qualitative comparison of the spectra, and their errors, of (from the top): (1) the intrinsically faint type I SN 2012hn (at 4 days before maximum, Valenti et al. 2014, note also the presence of bright nebular emission lines, such as Hα, [N II] and [S II], from the host galaxy); (2) the faint type IIb SN 2022ngb before peak luminosity (Izzo et al. 2022); (3) the modeled KN spectra of run7 viewed from edge on (cos θ = 0), (4) and face on (cos θ = 1) inclinations, as if they have been observed with MAAT/GTC using the grism R500 and an exposure time of 300 s, and being characterized by an observed magnitude of V = 21.5 mag.
