As mentioned in yesterday’s ADAP, last week the ATCA had an array reconfiguration, with the antennas moving from the compact H168 array into the extended 6D array. The four 6-km arrays (6A, 6B, 6C and 6D) all have a longest baseline (between antennas CA01 and CA06) of about 6km. The shortest baseline in 6D is the one pictured, the 77m baseline between CA04 and CA05.
