Synthetic spectrum of a consistent ALImI-model (right-hand side) and an LTE-model (left-hand side) used as a starting configuration for the primary iteration cycle, both compared with the spectrum of SN 1992A at early epochs (red line, see also Fig. 12). As is the case for the pure scattering model, both models preserve the total luminosity induced at the inner boundary. The shape of the spectrum resulting from the consistent ALImI-model reveals however a significant improvement when compared with the pure scattering model (Fig. 13) and the observations (especially in the blue part of the spectrum – shortward of 5000 Å – the differences to the observation are strongly diminished in the case of the ALImI-model). An improvement of the calculated spectral characteristics is also seen for the LTE-model, revealing that B_νr(T(r)) presents good starting values for the total line source functions S_L(r). The strong discrepancies of individual line shapes especially between 3000 Å and 6000 Å, however, shows that simulations intended for diagnostic purposes should not be based on LTE-models.
