TL;DR: The HIPASS data was acquired at the Australia Telescope National Facility's Parkes 64m telescope in 1997 February, and was completed in 2000 March as mentioned in this paper, and the characteristic root mean square noise in the survey images is 13.3 mJy.

TL;DR: In this article, the authors present a wide-field interferometric imager that uses the w-stacking algorithm and can make use of the W-snapshot algorithm, which is an order of magnitude faster than w-projection, as well as being capable of full-sky imaging at full resolution with correct polarization correction.
