$\star$ Factors of stretching

Figure 9.10 shows the comparison of the factors of stretching. We see that the relationship between the two estimates is equal to the factor of stretching which we estimated for the owner of lightcurve of SCP (equation 9.12 ). The figure shows a certain discrepancy between the two estimates (approximately 6%), this dispersion is reduced to 2% for the supernovæ with an error on the magnitude to the maximum lower than 0.03.
