摘要：

The use of the Tully-Fisher (TF) relation for the determination of H-0 relies on the availability of an adequate template TF relation and of reliable primary distances. Here we use a TF template relation with the best available kinematical zero point, obtained from a sample of 24 clusters of galaxies extending to cz similar to 9000 km s(-1), and the most recent set of Cepheid distances for galaxies fit for TF use. The combination of these two ingredients yields H-0 = 69 +/- 5 km s(-1) Mpc(-1). The approach is significantly more accurate than the more common application with single cluster (e.g., Virgo, Coma) samples.
