Abstract:
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 DE<+2° of HIPASS, the first blind HI survey
to cover the entire southern sky. RMS noise for this survey
is 13mJy/beam and the velocity range is -1280 to 12700km/s. Data
search, verification and parametrization methods are discussed
along with a description of measured quantities. Full catalogue data
is 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.
Description:
HI line data for 4315 extragalactic sources south of DE<+2°
are presented. Data measured from the southern HIPASS images is
provided, including positions, radial velocities, velocity widths,
integrated fluxes and peak flux densities.
