.........It was this special edition negative that was scanned completely in 2004 to create the high def masters for DVD and Blu Ray.

As far as I understand Lowry were handed the 2k files of the 97SE versions, which they were expected to clean up.

Yes that is correct.

Rick Dean of Lucasfilm/THX scanned the special edition negative at 1080 X 1920 resolution.

Seeing as that negative consisted of 3rd generation material----a 1080 X 1920 scan would capture all the information on that negative.

On edit:

Interestingly.....Star Wars's negative was shot in anamorphic.

The ratio of a 35mm anamorphic frame is actually 4:3 or 12:9.

Seeing as 1920 X 1080 resolution corresponds to a 16:9 frame

then 12:9 would correspond to 1440 X 1080

So an anamorphic frame scanned at 1920 X 1080 would leave unused 240 vertical pixels on either side of the 12(1440):9(1080) 35mm frame.

Once this is scanned into the computer this 1080 X 1440 image is stretched(scaled) horizontally to 1080 X 2500 to achieve the original scope 21:9 dimension.

CGI work/digital clean up is then done at this resolution.
