ASKAP-32 No amplitude calibration: no Tsys, no gain. First observations of this station. Positions and velocities on epoch 2000.0:

        ASKAP-32  X Coor      -2558276.03 -+ 0.16 m
        ASKAP-32  Y Coor       5095032.59 -+ 0.19 m
        ASKAP-32  Z Coor      -2850671.51 -+ 0.39 m 

        ASKAP-32  X Velo           -46.60         mm/yr
        ASKAP-32  Y Velo             6.26         mm/yr
        ASKAP-32  Z Velo            53.05         mm/yr

Velocity is taken from NUVEL-NNR model. Velocity was not adjusted.

ATCA-109 Fringe phase severly corrupted to the level that data are useless. Here are examples. I speculate that phasing up ATCA did not work for this experiment.

Results

20 out of 25 target sources had 3 or more used points. 5 non-detections:

Estimates of the correlated flux density

The correlated flux density is given in three ranges:

Flux₁: 0 – 6 Mλ
Flux₂: 6 – 25 Mλ
Flux₃: 25 – 50 Mλ
