Display units for translations in registration.txt

[meyer-usda]

Would it be possible to display the units for the translations in registration.txt? We are trying to apply a transformation found for a pair of DSMs onto an orthomosaic derived from the AOI DSM (and pointcloud). It seems like the units could be pixels or perhaps cm/mm but so far haven't found a conversion that fits the observed shift.

When viewing DSM and DSM_registered there appears to be a 10m shift in x and ~0m in Y. Understanding how this shift maps from the provided translations would be great, thanks!

The units should be whatever the units of the coordinate system of the data are provided with. CODEM shouldn't do any unit translation. Could the DSM vs DTM differences be some kind of aliasing effect?
