TL;DR: The Boolardy test array as discussed by the authors is a prototype of the Australian square kilometre array pathfinder telescope with a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously.

TL;DR: In this paper, the authors report the discovery of a 21-cm H I absorption system using commissioning data from the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP).

TL;DR: The Boolardy Engineering Test Array (BETA) as discussed by the authors is the first aperture synthesis radio telescope to use phased array feed technology, giving it the ability to electronically form up to nine dual-polarisation beams.

TL;DR: In this paper, the authors describe the algorithms used to distribute the data, find an appropriate threshold and search to that threshold and form the final source catalogue, and discuss the approach used to apply two-dimensional fits to detected sources, enabling more accurate parameterisation.
