I was able to correct my previous image of Atlas, Hercules and Endymion for foreshortening.
Here is the image of Atlas (215 kb)

and the larger image showing Atlas, Hercules and Endymion (84 kb).

I think the central crater ring in Atlas is clear. As usual, the correction for foreshortening is not linear across the image. Endymion is still slightly distorted even though Atlas and Hercules are almost completely corrected. The original size of the large image is quite large and detailed. I can send it separately to anyone who requests it.
