About this Dataset

Patheon SNe-IA Samples

The PANTHEON dataset

The PANTHEON dataset is a combination of observations from 3 subsets: 279 Pan-STARRS SN Ia (0.03 < z <0.68) with useful distance estimates of SN Ia from SDSS, SNLS, various low-z, and HST samples. This forms the largest combined sample of SN Ia, totaling 1048 SN Ia ranging from 0.01 < z < 2.26.

Columns

name : the name of the object
z : the redshift at which the object was observed
dist_modulus : the distance modulus "μ" measured
error : the measurement error

Distance modulus:

The distance modulus μ is the difference between the apparent magnitude, m and the absolute magnitude M of an astronomical object. It is related to the distance, d, in parsecs by:

$$
\mu = 5 \mbox{log}_{10} (d) - 5
$$
