'Bird-of-paradise' constellation sings a sweet tune for ASKAP

The field targeted for this observation is in the Apus ('bird of paradise’) constellation. This is the same field previously used to produce the first multi-beam image ever made with ASKAP PAFs, and used to analyse the benefits of ASKAP’s third 'roll' axis. This area of the sky has become a ‘standard’ test field for the ACES team, due to its proximity to the South Celestial Pole and that it contains an arrangement of several strong sources.
The resulting continuum image was produced using ASKAP’s dedicated imaging package, known as ASKAPsoft, and at 30 square degrees is equivalent to the telescope’s full field of view.
This image not only represents that ASKAP’s newest receiver systems work, but also that ASKAPsoft has matured to deal with large quantities of data and produce images of the same high quality as other well-established software packages.
