    Description

      This is a continuation of the work in SP-1033. We now have integrated beam patterns into existing imagers and are able to produce high quality simulations using heterogenous array configurations.

      The next step is to investigate mitigation techniques for heterogeneous beam effects in the image plane via the use of existing imagers that model these effects during convolutional gridding (DDFacet, wsclean) and during model prediction (MFBeam). We should compare the relative accuracy and speed of the various methods on simulated datasets and investigate the level of interpolation required in the beam models to meet the dynamic range requirements of MeerKAT+.
