Abstract A Bayesian approach is used to derive the probability distribution (PD) of the Hubble constant H0 from recent measurements including supernovae Ia, the Tully-Fisher relation, population II and physical methods. The discrepancies among these PDs are briefly discussed. The combined value of all the measurements is obtained, with a 95% confidence interval of 58.7 < H0 < 67.3 (km.s-1.Mpc-1).
