Description
In v20.0.0, the corner rafts CCDs are laid out like this:
The guider chips are correct (according to LCA-13381), and the locations of the wavefront CCDs, R44_SW0 and R44_SW1, are correct, but the amps are mis-labeled.
In v21.0.0, the corner raft layout looks like
The left-to-right orderings of the amps of the wavefront chips are now not correct, but and R44_SW0 is shifted upwards and R44_SW1 is shifted downwards relative to their nominal positions. Similar problems are seen for R00, R04, and R40. These new placements were added in DM-26205.
