Overscan/bias residuals

Issue raised Apr 30 2016, 16:22 AEST; last modified Jun 21 2017, 16:03 AEST

The EDR overscan and bias show residuals varying from image to image and row to row. This originates from a temporally unstable bias that can vary by up to ten counts within an image row. There is also a diagonal electronic interference noise.

These two deficiencies have been substantially mitigated in DR1.
