A Study Of Potential Calibrators Using The KAT-7 Telescope

Abstract

We studied Active Galactic Nuclei (AGN) as potential calibrators, which were observed by the Karoo Array Telescope (KAT-7) between Oct 13, 2012 and Feb 23, 2013. The KAT-7 is an engineering prototype for the coming sensitive array, the MeerKAT, one of the pathfinders for the Square Kilometer Array (SKA). The KAT-7, whose construction started in early 2008, has been undergoing engineering and science verifications since late 2010. In this presentation, we report the flux-density and position measurement accuracy of the KAT-7. Moreover, we explain the first steps towards identifying possible flux-density standards using variability metrics for short baseline interferometers such as the KAT-7.
