Figure 2: The spectrum of 497 Iva in the visible region, with errorbars. This spectrum exhibits monotonic behavior with a slightly positive slope. The edge of the spectrum is less reliable because of limitations of the instrument and detector (http://www.tng.iac.es/instruments/lrs/). |

Figure 3: Modified Gaussian Model applied to asteroid 766 Moguntia. Two absorption bands (light green) associated with olivine were used to model the experimental data, by using free parameters option. The error between the real spectrum and the best fit is presented in red. The best fit (turquoise) suggests a surface dominated by olivine minerals. |
