Abstract

Following Gott et al. (2001), we use Huchra's final compilation of 553 measurements of the Hubble constant (H0H_0) to determine median statistical constraints on H0H_0. We find H0=68±5.5H_0=68 \pm 5.5 (or ±1\pm 1) \kmsmpc\kmsmpc, where the errors are the 95% statistical and systematic (or statistical) errors. With about two-third more measurements, these results are close to what Gott et al. found a decade ago, with smaller statistical errors and similar systematic errors.
