标题： Distances from the Correlation between Galaxy Luminosities and Rotation Rates

摘要： 一个大的光度-线宽模板样本现在可用，已经得到了改进的吸收修正，并且有统计上显著数量的星系具有确定的距离以提供零点。 对哈勃常数的重新估计为 H_0=77 +-4 km/s/Mpc，其中误差是95%概率的统计误差。 系统不确定性可能大两倍。 显示英文摘要

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. A revised estimate of the Hubble Constant is H_0=77 +-4 km/s/Mpc where the error is the 95% probability statistical error. Systematic uncertainties are potentially twice as large.
