 Taking the largest rotation angle separation available in the currently studied ghost data (processed with added verbosity to extract reference/model positions, and checked manually for true ghost centers), there does not seem to be significant disagreement among the exposures with different rotation angles (using ROT header keyword).  The large offsets found on the top and bottom edges of the FPA appear in both exposures.
 
+After further study of this image, I realized that I'd neglected to correctly account for the OTA/FPA parity issues that result in flips of coordinate systems.  I've replotted the vector diagram with these parity issues resolved:

+I suspect that this was the main issue preventing a useful ghost model being constructed from this data before.
