Maplet residuals (a, b), maplet formal uncertainty (c, d), and vertex sigmas (e, f) for our Phobos global SPC model. These metrics indicate a model accuracy of ± 13–20 m and a precision of ~ 4 m (5 × the mean vertex sigma). A few localized areas stand out in these metrics; these areas are associated with crater walls in areas where most images are heavily shadowed
