Overscan/bias residuals


Issue raised Apr 30 2016, 06:22; last modified Jun 21 2017, 06:03

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.
