Upper panel: view of the Hathor region. Image NAC_2014-08-07T20.20.34 (spatial resolution: 1.5 m pix^-1). The red circle shows an example of a smooth terrain on slopes in the range 25−30°. Green circles show examples of overhangs with slopes >90°. Lower panel: extracted Digital Terrain Model (left) of the Hathor region with the corresponding gravitational slopes (right) computed from the SPC shape model (Jorda et al. 2015). For technical reasons related to the DTM extraction, we were not able to produce a figure for Hathor like Figs. 1−3, or 5.
