This image focuses on the cliff-like region in Seth and Babi on Comet 67P/Churyumov–Gerasimenko’s large lobe and their boundary with the neck region, Hapi.
An annotated version indicating the boundary between Seth and Babi can be found here.
The image was taken on 10 September 2014 when Rosetta was about 27 km from the comet surface.
