The HIPASS catalogue - I. Data presentation
The HI Parkes All-Sky Survey (HIPASS) catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The catalogue data comprise the southern region δ < + 2° of HIPASS, the first blind HI survey to cover the entire southern sky. The rms noise for this survey is 13 mJy beam-1 and the velocity range is -1280 to 12 700 km s-1. Data search, verification and parametrization methods are discussed along with a description of measured quantities. Full catalogue data are made available to the astronomical community including positions, velocities, velocity widths, integrated fluxes and peak flux densities. Also available are on-sky moment maps, position-velocity moment maps and spectra of catalogue sources. A number of local large-scale features are observed in the space distribution of sources, including the super-Galactic plane and the Local Void. Notably, large-scale structure is seen at low Galactic latitudes, a region normally obscured at optical wavelengths.
