15.1 UV coverage and beam size

UV coverages can be generated (and saved to a UV table if needed) using command ARRAY to define which telescope array is being used, followed by command UV_TRACKS which is used to define the array configuration, the source declination and the observing frequency. IMAGER has a number of built-in arrays available, but the user may define its own (e.g. for array design, or specific experiences using sub-arrays) using the ARRAY USER command.

Command UV_TRACKS can be used repetitively for multi-configurations.

Once the UV coverage is written, the usual commands READUV, UV_STAT WEIGHT, or UV_STAT BEAM can be used to derive the dirty and the clean beam size.
