Line 35:

The telescopes are provided by the European, North American and East Asian partners of ALMA. The American and European partners have each placed orders for twenty-five 12-meter diameter antennas, that will compose the main array. East Asia is contributing 16 antennas (four 12-meter diameter and twelve 7-meter diameter antennas) in the form of the Atacama Compact Array (ACA) which is also part of the enhanced ALMA.

By using smaller antennas than ALMA, larger fields of view can be imaged at a given frequency using ACA. The abilityMoving tothe move themantennas closer together alsowill results inenable the possibility toimaging imageof sources of larger angular extent. The ACA will work together with the main array in order to enhance the latter's wide-field imaging capability.
