Degeneracy between the blackbody temperature and the inferred emitting area (or velocity) for a given NIR continuum. The X-shooter epoch 4 spectrum is overlaid with blackbodies of various temperatures and areas that produce similar NIR flux levels. The observed NIR features can be modelled as P Cygni or pure emission components, but make the exact underlying continuum difficult to estimate precisely. If the near-observed infrared features are produced by La III and Ce III for LTE conditions, these species must reside in relatively hot ejecta. Hotter ejecta produces a higher NIR continuum flux, which would conversely require a smaller emitting area or lower velocity to match the observed continuum. While the optical P Cygni features are consistent with the observed blackbody temperature and velocity, these NIR identifications would need higher temperatures and be spatially distinct from their optical counterparts.
