Cumulative distribution of uv points as a function of uv radius. Yellow line shows best fitting gaussian uv density distribution. Fig 2 Plan of optimised zoom spiral array used for simulations. Mean baseline length is 982m and median is 921m. Cumulative distribution of uv points as a function of uv radius.
Yellow line shows best fitting guassian uv density distribution.
Fig 3 Plan of donut-0.25 Kogan optimised array, scaled to have the same resolution as the zoom spiral in Fig 1. Mean baseline length is 924m and median is 941m. Cumulative distribution of uv points as a function of uv radius. All data are weighted equally. The peak sidelobe in the donut case occurs within a ring like near-in sidelobe and have a level of 0.0414.
