A comparison of the neck area (Hapi with Hathor and Seth). The model shows erosion (model A) integrated over one spin on 12 September 2014. The strongest erosion is on a cliff in the Ma’at area (see Fig. 15) The erosion along Hapi is concentrated at the foot of the Hathor wall. The enhancement is visible as a yellow band. The surface temperature (based on model C) is as expected also high in that region, depending on the local time of day.
