   * After completing the initial fringe-fitting (using the default settings defined by /data/AUSTRAL/cf_aust), you will be prompted to enter a command like "cd /data/AUSTRAL/aug013/1344 ; export CORDATA=/data/AUSTRAL/aug013/ ; export DATADIR=/data/AUSTRAL/aug013/ ; aedit -f alist.ed.out". Do so, and you will be able to make a first inspection of the data.   * After completing the initial fringe-fitting (using the default settings defined by /data/AUSTRAL/cf_aust), you will be prompted to enter a command like "cd /data/AUSTRAL/aug013/1344 ; export CORDATA=/data/AUSTRAL/aug013/ ; export DATADIR=/data/AUSTRAL/aug013/ ; aedit -f alist.ed.out".

 After running "edi dup snr", run "psplot" and check for either grey scans (uncorrelated data) or brown ones indicating non-detections. If found, make sure there's a sensible/known reason for them (module failure, antenna windstowed, etc). If there's no explanation, get in contact with the correlator ASAP.  After running "edi dup snr", run "psplot" and check for either grey scans (uncorrelated data) or brown ones indicating non-detections.

To do this, pick a scan with good SNR (50+) in both bands - you can check this within aedit with  If you have a station with no [or weak] phase-cal, you will need to do a manual pcal.
