Fig. 8


Radiance factor (IF) as measured by VIR at 0.55 μm against the modeled values (IFm) at the corresponding observation geometry, for different solutions of the Hapke model discussed in Sect. 3.3: S2 (a), S3 (b), and S4 (c). The black line in each plot indicates the ideal behavior IF = IFm. The color in the contour plots is proportional to the square root of the point density after normalization of the maximum value to unity.
