Propagation of incomplete angular constraints into the inferred single-scattering albedo spectrum for the RELAB spectrum BIR1DD065 of olivine from the Martian meteorite NWA 2737. Top: laboratory reflectance spectrum used as the input constraint. Middle: ensemble of inferred ω(λ) solutions obtained by sampling the angular-scattering parameters (b, B₀, h) and inverting the Hapke model wavelength-by-wavelength to reproduce the measured reflectance at the laboratory geometry (i₀, e₀, g₀) = (30^∘, 0^∘, 30^∘). The solid line shows the median, the darker shaded region encloses the 16th–84th percentile interval, and the lighter shaded region shows the full range of solutions. Bottom: fractional 16th–84th percentile spread in the inferred single-scattering albedo, (ω₈₄ − ω₁₆)/ω_median.
