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.
After checking with Robert Lupton, I confirm that using v21.0.0 does assemble the BOT data correctly. Here's the Flammarion assembly from August 2020 using v21.0.0 and cameraGeom.showCamera:
However, when running corner_raft_plot.pyto produce the R44 layout plots, the WF CCD placements are incorrect. I suppose it's possible there's a bug in this script, but if not, the difference in behavior between that script and .showCamera should be understood.
FWIW, this modification of R44W.yaml places and orients the WF chips in roughly the right places:
