The first interferometric tests carried out on three Mk II phased array feed receivers recently installed at the Murchison Radio-astronomy Observatory (MRO) have confirmed the in-the-field performance of the newest receiver systems developed for ASKAP.
The results are a significant step towards the full ASKAP telescope, and achieved so quickly largely thanks to the valuable experience gained during commissioning of the Mk I PAFs (the six-antenna telescope also known as the Boolardy Engineering Test Array, or BETA).
