This small module was written for CosmoSIS.

Supernova type IA measurements are a standard(izable) candle that can be used to probe the relation between luminosity distance and redshift. At low redshifts this directly probes the Hubble parameter, H0.

The Riess et al 2.4% solution measurement of H0 is used in this module.

Assumptions

  • FRW cosmological model
