The first section discusses a recalibration of the luminosity–linewidth technique and its use in a determination of H0. The recalibration introduces (i) new cluster calibration data, (ii) new corrections for reddening as a function of inclination, and (iii) a new zero-point calibration using 13 galaxies with distances determined via the cepheid period–luminosity method. It is found that H0 = 82 ± 16 km s−1 Mpc−1 (95% confidence).
