Figure 8From: Cassini/VIMS observes rough surfaces on Titan’s Punga Mare in specular reflectionSurface facet angular deviation. This image, which corresponds to the pixel geometry from cube CM_1721848119_1 as shown in Figure 1, represents how far the orientation of a surface facet would have to be tilted at each location in order to achieve a specular geometry with the Sun. This value, which we call the specular facet deviation θ, varies across Punga Mare from 3.4° at the end nearest to Kivu Lacus to 10° at the far end.Back to article page
