Figure 7
Top: map of surface angle θ computed from the Ca-Kα fluorescence map of Fig. 6[link]. Bottom left: rendering of surface of the scanned area, computed from the surface angle map above and shaded as if obliquely illuminated from the right-hand side by a light source. The reconstruction gives a clear and detailed picture of the surface relief, including the fine horizontal rulings at the top and bottom (marked by arrows). Bottom right: photograph of the scanned area, adjusted to enhance contrast and brightness.
