  Observational parameters which can be used for redshift-independent distance
determination using the Tully-Fisher (TF) technique are given for 782 spiral
galaxies in the fields of 24 clusters or groups. I band photometry for the full
sample was either obtained by us or compiled from published literature.
Rotational velocities are derived either from 21 cm spectra or optical emission
line long--slit spectra, and converted to a homogeneous scale. In addition to
presenting the data, a discussion of the various sources of error on TF
parameters is introduced, and the criteria for the assignment of membership to
each cluster are given. The construction of a TF template, bias corrections and
cluster motions are discussed in an accompanying paper.
