$\star$ Comparison for 2000fr

The supernova 2000fr was analyzed in an independent way in the same article and our analysis. It thus was used us as point of comparison for the two analyses.

Table 9.1 shows the parameters of the lightcurve estimated by the two methods.

In spite of a relatively different approach, we see that the estimates are in very good agreement. The difference between the two factors of stretching is due to difference between the two models of curves of light. We check well that $1.01/0.96 = 1.06$.
