Each of the ATCA's possible array configurations are listed below. For each array, the station locations are listed for each antenna, and whenever an antenna can be located on multiple stations in that configuration, all the variants that have been used are listed. For the most used variant of each configuration, the baseline lengths are shown, in metres.
Configurations within each group of 4 (ie. 6A, 6B, 6C, 6D), or in one of the complementary array groups (designated as a, b, c, d and e) form complementary sets for multi-day observations. Note: This is for single-frequency observations. For a more sophisticated approach, see the section on bandwidth and multi-frequency synthesis.
CA06 sits permanently on station W392. Baselines to this antenna are shown for all configurations, but form part of the design only for the 6 km configurations (6A, 6B, 6C and 6D).
