obs_description      = The `HI Parkes All Sky Survey' (HIPASS) covers the whole southern sky as well as northern declinations up to +25 degrees. HIPASS commenced in Feb 1997, and the last northern scans were taken in 2002. HIPASS was carried out with the Australia Telescope National Facility's Parkes telescope Parkes 64-m telescope equipped with a novel 21-cm multibeam system. The latter comprises a cooled, 13 beam receiver and digital correlator (Staveley-Smith et al. 1996, Wilson et al. 1997 and Sinclair et al. 1997). The 64 MHz observing band, centred on 1394.5 MHz, was divided into 1024 channels, providing a velocity range of -1280 < cz < 12700 km/s with a channel width of approx. 13.2 km/s and a velocity resolution of 18 km/s. The HIPASS integration time per beam is 450s. After gridding an r.m.s. noise of about 13.3 mJy was achieved in the first set of HIPASS cubes. The observations and techniques used to calibrate and image the data are described in Barnes et al. (2001). The processing algorithms are successfully designed to be statistically robust to the presence of interference signals and are particular to imaging point (or nearly point) sources, not extended emission. Specifically, a major improvement in image quality is obtained by designing a median-gridding algorithm which uses the median estimator in place of the mean estimator. While the average Parkes beam FWHM is 14.3 arcmin, the average gridded HIPASS beam is about 15.5 arcmin. The full data release contains data from 538 data cubes (size: 8o x 8o, 388 over the entire southern sky (DEC < +2o), and 150 over the northern sky, (DEC < +25o). The one-dimensional spectral data for a given position is available for downloading in a variety of different formats.
