Image Details
Caption: Figure A1.
Shows plots of the best-fit spectral models (step 6) for all ROIs (including the reference regions) across the three temperature ranges. Each panel shows the NIMS reflectance spectrum (blue points), 2σ uncertainty envelope (shaded), and the combined best-fit model (orange dashed line). The corresponding end-member contributions are indicated in the legend.
