Abstract:
The correlation between the luminosities and rotation velocities of
galaxies can be used to estimate distances to late-type galaxies. It
is an appropriate moment to reevaluate this method given the great
deal of new information available. The major improvements described
here include: (1) the template relations can now be defined by large,
complete samples, (3) the samples are drawn from a wide range of
environments, (3) the relations are defined by photometric information
at the B, R, I, and K' bands, (4) the multiband information clarifies
problems associated with internal reddening, (5) the template zero
points are defined by 24 galaxies with accurately known distances, and
(6) the relations are applied to 12 clusters scattered across the sky
and out to velocities of 8000km/s.
