Data Quality Observations
The observations were intended to check that there are no gross problems with the array and to monitor the long-term quality of the data produced by the array. A 12 hour observation of simple sources also allows a better understanding of the array performance to be developed. A final goal is form a deep image of the blank fields from the accumulated observations.
Statistics are gathered on closure phase of the calibrators, dynamic range of the images, and fraction of data flagged. The reduction of these data quality observations is automated.
