We decided that the contrast is not as apparent if the step occurs further out in the corona. We decided to take the first correct anc copy it into the cortab0.current and call that good. Scan looks good at high gain throughout the height.

There may be contamination on the detectors but that would involve removal to inspect and all alignment will be lost in doing so. At this point in the ACOS program, that would not be an option. We decided to live with the ring as it occurs in a region that is well covered by the MKIV.
