Abstract: | In a recent series of papers, Sandage and Tammann reach the conclusion according to which the Hubble constant is everywhere the same. This result arises from the analysis of two samples (a nearby one and a remote one) of Sc-type galaxies, each sample separately giving the same <H0> mean value. We attempt to check whether or not the whole data from both the samples together are consistent with theH0=constant hypothesis at a suitable level of statistical significance. |
