Full HIPASS data release

The full HIPASS database is now available on-line at www.atnf.csiro.au/research/multibeam/release.

Data from the HI Parkes All-Sky Survey (HIPASS) for Declinations less than + 2 degrees were released on 13 May 2000. Spectra for any position can now be downloaded from the above web address in a variety of formats (fits, ascii, postscript, gif). The velocity range of HIPASS is - 1200 to 12700 km/s and the rms noise is 13 mJy/beam. On 29 June 2000, the www interface was upgraded to Version 2, allowing selection of different plotting parameters on the same page as the spectrum appears. The figure below shows an example spectrum of NGC 6744. As of Aug 21, Version 1 of the interface has ceased working (following an upgrade to Perl), so please change your bookmarks if necessary!

HIPASS public data release - v1.2 May 13 2000

The data available via the web has a spatial binning size of eight arcmin (compared with the 15.5 arcmin resolution of HIPASS) but are otherwise identical to the cubes available to the HIPASS team. We plan to enable access to the four arcmin pixel data, and to sub-cubes later in the year. This involves re-writing the www interface in Glish and AIPS++ rather than the existing Perl/Miriad interface, so this is a major exercise.

Data for the northern extension continues to be taken at Parkes telescope. Coverage of the sky between Declinations +2 and +25 degrees is 76 per cent complete and should be completed in 2001.Observations for the deep Zone of Avoidance survey are complete and are currently being gridded.
