Abstract
The optical and near-infrared Tully-Fisher relations are examined for an H i-selected sample of galaxies. This sample is unique in that membership is simply defined by the overlap of blind 21-cm, optical and near-infrared catalogues, rather than pre-selecting candidate Tully-Fisher galaxies for which to obtain rotational measurements. Three fundamental questions are considered: (i) Does the scatter depend on a third variable? (ii) What is the intrinsic scatter of the relationship? (iii) What is the slope of the z = 0 relationship as a function of wavelength, and can a single slope relationship be obtained by converting to stellar or baryonic mass? The H i Parkes All-Sky Survey (HIPASS) Catal..
