Cosmicflows-4: The Catalog of ~10000 Tully-Fisher Distances
  We present the distances of 9792 spiral galaxies lying within 15,000 km/s
using the relation between luminosity and rotation rate of spiral galaxies. The
sample is dominantly, but not exclusively, drawn from galaxies detected in the
course of the ALFALFA HI survey with the Arecibo Telescope. Relations between
\hi line widths and luminosity are calibrated at SDSS u, g, r, i, z bands and
WISE W1 and W2 bands. By exploiting secondary parameters, particularly color
indices, we address discrepancies between measured distances at different wave
bands with unprecedented detail. We provide a catalog that includes reduced
kinematic, photometric, and inclination parameters. We also describe a machine
learning algorithm, based on the random forest technique that predicts the dust
attenuation in spirals lacking infrared photometry. We determine a Hubble
Constant value of H0 = 75.1+-0.2 (stat.), with potential systematics up to +-3
km/s/Mpc.
