For a subsample of 6dF a peculiar velocity survey is measuring mass distribution and bulk motions of the local Universe.

[3] All redshifts and spectra are available through the 6dFGS Online Database, hosted at the Royal Observatory, Edinburgh.

The survey was carried out with the 1.2 meter UK Schmidt Telescope at Siding Spring Observatory in New South Wales, Australia with the 6dF instrument permitting the observation of a field of 6 degrees per pointing.

The low redshift of 6dF made it possible to derive the Hubble constant H0 with an uncertainty competitive with the distance ladder technique.

[6] This requires measurements of the galaxies' internal velocity dispersions which is much more difficult than the determination of the redshift.
