Image Details
Caption: Figure 4.
Bidirectional reflectance is presented for (a) ilmenite, (b) hematite, (c) spinel, and (d) LHS-1 with grain size <20 μm. Each graph illustrates reflectance intensity as a function of emission angle across multiple spectral bands and with an incidence angle of 0°. Trend lines are fourth-degree polynomial curves.
