Irregardless of what application is using the Ridge files, the application
should use the map reference provided by the authors.  Obviously, the Geo
Files should use the center of the upper left pixel as a reference point to
calculate the other needed points.

I offered to provide you the ridge table earlier but you were not
interested.  FindU used the RIDGE table I provided to generate the needed
references.  I would be happy to provide the table to anyone who requests
