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: The Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope as mentioned in this paper is one of the first radio telescopes to deploy phased array feed (PAF) technology on a large scale, giving it an instantaneous field of view that covers and is expected to facilitate great advances in our understanding of galaxy formation, cosmology, and radio transients while opening new parameter space for discovery of the unknown.

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, a 3-yr study of the 15-GHz variability of 51 9C sources was conducted, and the results showed that 29 per cent of the sources were found to be variable above the flux calibration uncertainties of ~6 per cent.
