| Abstract | The Cosmicflows database of galaxy distances that in the second edition contained 8188 entries is now expanded to 17,669 entries. The major additions are 2257 distances that we have derived from the correlation between galaxy rotation and luminosity with photometry at 3.6 μ {{m}} obtained with the Spitzer Space Telescope and 8885 distances based on the Fundamental Plane methodology from the Six Degree Field Galaxy Survey collaboration. There are minor augmentations to the Tip of the Red Giant Branch and Type Ia supernova compilations. A zero-point calibration of the supernova luminosities gives a value for the Hubble Constant of 76.2+/- 3.4+/- 2.7 (± rand. ± sys.) km s-1 Mpc-1. Alternatively, a restriction on the peculiar velocity monopole term representing global infall/outflow implies {H}0=75+/- 2 km s-1 Mpc-1. |
