      Understanding the effect of heterogeneous beams on imaging performance, and how this influences design parameters such as integration time and self-cal cycles is vitally important.

    Description

      A follow on from the work in SP-654, we now have a framework in place to produced simulated visibilities using the MeerKAT+ array configuration with two classes of beam patterns.

      The next step is to being exploring a range of parameters in the imaging chain to see their effect on overall image quality when working in the heterogeneous regime (e.g. source positions, self-cal levels, frequency dependence, etc...).

      This work will also be used to evaluate the time and frequency averaging strategies for MKAT+ and make a recommendation on these parameters.

      As a stretch an evaluation of existing mitigation techniques will be undertaken. As a first pass this will include MFBeam (degredding solution) and DDFacet (AWProjection).
