Pipeline issues noted by staff:
ea05 gain amplitude solutions show a split about half way through the observation.
ea14 gain amplitude solutions are low for a few scans.
ea17 gain ampliutde solutions are very high for a few scans.
ea26 gain amplitude solutions are low for some scans.
The complex gain calibrator shows decorrelation, primarily from scan='2,33~50,54,59,63~69,73'.
