Hi Brad,

As we discussed offline, your headers contain a deprecated keyword EPOCH that contained the epoch of observations rather than the epoch of the plate solution (which should be 2000.0). When the plate solution was updated by AIJ, it failed to remove the old keyword.

Builds 3.4.0.17 and later will now remove the old EPOCH keyword which will solve this problem.

You will need to re-plate-solve your images to make the correction, or you can go in and by hand delete the EPOCH keyword from each image using the FITS Header Editor.
