Posterior distributions of the geometric albedo A_g predicted under the three conditioning schemes considered in this work. The violin distributions show the posterior geometric albedo A_g for the single-geometry retrieval (left), the single-geometry retrieval supplemented by grain-scale optical constraints (center), and the full multiangular retrieval (right). Black points and vertical bars indicate the posterior medians and 16th–84th percentile intervals, respectively. The individual posterior samples are shown as faint black points.
