Notes. For each sample are listed the mean absolute magnitude, the systematic luminosity scatter, the weighted observed scatter around the Hubble line, and the number of used and total SNe. (a) χ2∕d.o.f. < 1 even with σB,intr = 0.0 mag. (b) Weighted standard deviation. (c)Weighted standard deviation of all points around the Hubble line. Its uncertainty is 0.007 mag.
