I attempted to re-reduce a Keck/DEIMOS dataset to produce a better WCS solution using the most recent version of POTPyRI on Burbidge. In the final stack, multiple copies of the same object appear in the vicinity of the actual objects. I inspected each individual frame (science and calibration) and have ensured that the data going in are ok. The field has a limited number of Gaia calibrators. The data and re-reduction attempt can be found at /data/Keck/FRB20230807_redux_v2/ on burbidge (note: I made a typo in the directory name, the FRB is actually named 20230827; the above path is correct though).
