Summary
The methods given above will enable the BBD of an HIselected sample of galaxies from HIPASSto be determined. The sample will be free of optical selection effects, although we may still suffer some discrimination against LSBG's due to column-density limits and profile shapes.
In determining the BBD we will investigate the significance of LSBG's in the population of galaxies as a whole and will determine how the luminosity function varies with surface brightness. This will answer the question as to whether or not HIrich giant LSBG's make up a significant fraction of the population of giant spirals.
We have developed a galaxy finder that can be used to extract a catalogue from the HIPASScubes in order to obtain an objectively selected sample of galaxies. The finder is still under development but is giving acceptable reliability and similar numbers of true galaxies to by-eye searching. It also delivers a parameterization of the galaxies found, including the HImass that is of prime importance in determining the sample and V/Vmax.
