... Erdogdu, P. , Ettori, S., Lahav, O. 2002 Estimates of Omega_m and H_0 from Baryon Mass Fraction in Clusters of Galaxies and Cepheid-Calibrated Distances ( astro-ph/0202357 ) . ...
... Eight nearby Type Ia SNe-host galaxies have now had their distances determined via HST-observed Cepheids, providing an absolute calibration to the far- eld SN Hubble Diagram, which in turn provides a (presumably!) accurate determination of the Hubble ...
... For example, angular diameter measurements of Cepheids are currently felt to be more valuable than angular diameter measurements of solar-type stars. ...
