First Fringes on the North Spur
The ATCA was reconfigured into the H75 configuration on 12 August, which includes
CA02 and CA03 on the north spur, and CA04 at the intersection of the north spur
and the east-west track. None of these stations had been used for
astronomy before.
At 17:28 that afternoon, antennas stationed on the north spur produced
their first astronomical interferometric fringes.
After re-calibration, the first image was made from 6 hours of observing.
First clean fringes with the north spur.
Five antennas tracking 1934-638.
Fourier coverage and image of J0116-473 at 8.9 GHz, from 6 hours of observing. Resolution is 40 arcsec.
The image is from a 9-pointing mosaic.
