Title
Testing Linear Spectral Unmixing On Laboratory Mixtures: Application To Vir Data For Asteroid Vesta.
Abstract
At 525 km in mean diameter, Vesta is the second largest object of the main asteroid belt [1, 2]. The Visible and InfraRed (VIR) spectrometer onboard Dawn provided more than 20 millions spectra at variable spatial resolution, allowing one to discriminate the different lithologies on Vesta [3, 4, 5]. In this work, we tested linear spectral unmixing on three different mixtures, to verify the applicability of linear unmixing to VIR data of Vesta, and to determine the accuracy of the detection of the amount of the different minerals. We studied the following mixtures: two pyroxenes, pyroxene and olivine, and pyroxene and plagioclase. We next applied linear spectral unmixing to VIR spectra for localized features and larger areas, with the goal of deriving the composition and abundance of the minerals present.
