ATCA recording on cave-store.

DAS profile is vsop_n.pro, opposite of what is on daspro. Recording from DAS1 only.

Tied array of 12345.

Enabled automatic phasing of the array on the phase calibrator 1534-535. This turned out to be a very weak calibrator, and the phasing did not work very well for it. More troubling, even though the correlator could easily see a flat phase on the cross-pols, the cross-pol phase for all antennas except the reference antenna (CA03) seemed to change randomly on each phase cal. The polarisation purity of this experiment will probably be quite poor, as will the overall sensitivity of the array for that matter.
