The Atacama Compact Array (ACA), also known as the Morita Array, is composed of twelve closely spaced 7-meter antennas (7-m Array), and four 12-meter antennas for single dish observations (Total Power Array). The array is designed to enhance wide-field imaging in full ALMA operations. See Section "The Atacama Compact Array" of the ALMA Technical Handbook for more information.
