Abstract:
The data from photometric and spectroscopic observations of 1355
southern spiral galaxies are presented and used to determine their
distances and peculiar velocities via the Tully-Fisher (TF) relation.
I-band CCD surface photometry was carried out using the 1-m and 3.9-m
telescopes at Siding Spring Observatory. H-alpha rotation curves for
965 galaxies and 551 H I profiles are presented. The physical
parameters, photometric and velocity data, distances, and peculiar
velocities of the galaxies are presented in tabular form. The mean
distance, systemic velocity, and average peculiar velocity of 24
clusters in the sample are given. TF diagrams are presented for each
cluster.
Description:
Photometry of spiral galaxies less than about 5' in diameter was
obtained in the Kron-Cousins I passband at the 1m f/8 telescope at
Siding Sping Observatory. The 64m radio telescope at Parkes
Observatory, CSIRO,was used to obtain HI profiles of 551 galaxies.
