Has someone come up with a way to de-warp an object seen as an Einstein ring? I thought I had read someone doing this, but maybe it was they were trying to do this. Maybe it was during the discussion on using Sol as a gravitational lens like this?? Seems like some interesting math to put the image in TFA back into the shape of a galaxy.
Dewarping it mathematically should be fairly easy if the lens' gravitational field is sufficiently uniform. Problem is more the amount of detail we actually have in these pictures to expand the most compressed parts.
