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 3% solution measurement of H0 is used in this module.
