摘要: A large luminosity-linewidth template sample is now available, improved absorption corrections have been derived, and there are a statistically significant number of galaxies with well determined distances to supply the zero point. revised estimate Hubble Constant H0 = 77±4 km s−1 Mpc−1 where error 95% probable statistical error. Systematic uncertainties potentially twice as large.
