Description
In this paper we describe a methodology to be used for the automated
analysis of the spectroscopic contents of the GAUDI archive. We perform
chi-square minimisation in the 5000-5200 Å spectral window to
infer the atmospheric parameters and their random internal
uncertainties. Effective temperatures are anchored using a zero-point
correction into the scale defined by the method described in Ribas et
al. (2003). Surface gravities and metallicities were put in the scale
defined by nearby stars included in the S^{4}N archive. Comparison with
the Elodie.3 stellar library has shown excellent agreement. Our final
goal is to build a VO application, available from the Spanish Virtual
Observatory (SVO, http://svo.laeff.inta.es), to derive physical
parameters of large samples of stellar objects in an automated and
uniform way.
