Montage of spectra for models he2p6, he3p3, he4p5, he6p0, he8p0, and he12p0 at 200 d showing the wavelength region around 6300 Å (left), around 10 800 Å (middle), and around 20 000 Å (right). In all plots, we overplot the emission associated with bound-bound transitions from He I, N II, Fe I, and Fe II. The same species set and color coding is used even when some species or ions do not contribute flux to the selected spectral region.
