The automated stellar classification algorithm, MATISSE, has been developed at the
Observatoire de la Côte d’Azur (OCA) as a means of determining stellar effective
temperatures, surface gravities and chemical abundances for large samples of stellar
spectra. MATISSE is one of the key programmes to be used in the analysis of the spectra
that will be obtained by the Radial Velocity Spectrometer (RVS) on the European Space
Agency’s (ESA) Gaia satellite. In preparation for the Gaia mission, rigorous testing of
MATISSE is currently being carried out using large datasets of spectra from the European
Southern Observatory (ESO) archive (The AMBRE Project, a collaboration between ESO and
OCA). The derived stellar parameters will be delivered to ESO in order to make them
available to the astronomical community via the Virtual Observatory. This paper presents
the preliminary results of the analysis of the archived FEROS spectra.
