Comparison of beam weights and CB shapes. Left: beam weights for Beam 18 on 2019/08/22 for antenna RT8 (top) and RTB (bottom). Each pixel corresponds to an antenna element on the PAF. Broken elements are white pixels in the image. Right: corresponding CB map from a drift scan measurement. White contour levels are: 0.2, 0.4, 0.6, 0.8. Red contour levels are: 0.1 and 0.5. The colour scale is the same for all four images. Most of the signal for a given beam is contributed by nine antenna elements. If one of these antenna elements is broken, the CB for the given antenna will be distorted. In this case, two of the highest contributing elements on antenna RTB were broken.
