Validation on the planetary microlensing event MOA-2022-BLG-091. Panels (a) and (c) show the published 50 × 50 maps (Figure 2 of C. Han et al. 2025) with discrete color bands at Δχ² < 4, 8, 12, 16,  and 20 (red to blue). Panels (b) and (d) display the continuous Δχ² surfaces computed with lenscape at 400 × 400 resolution. Top row (a), (b): ﹩(\mathrm{log}s,\mathrm{log}q)﹩ plane. Bottom row (c), (d): trajectory angle α versus ﹩\mathrm{log}s﹩, with χ² profiled over all remaining parameters (including q) at each grid point.
