At least some of the existing MDI JP2 files are missing the CRVAL* keyword. These JP2 files are old, and so it is possible that the FITS files they were made from were missing the CRVAL* values.
Recently downloaded MDI FITS files do have the CRVAL* keyword. Therefore, the MDI JP2 FITS files should be remade.
