Band ratio and band parameter results for (a) ilmenite, (b) hematite, and (c) Mg spinel. We computed band ratios and band parameters on the pure LHS-1 spectrum (0 wt% target mineral) to assess a detection threshold. Since LHS-1 contains 0.4 wt% ilmenite, the first band ratio value was adjusted to start at 0.4 instead of 0.
