Abstract
The data analysis software (DAS) for VLT ESPRESSO is aimed to set a new
benchmark in the treatment of spectroscopic data towards the
extremely-large-telescope era, providing carefully designed, fully interactive
recipes to take care of complex analysis operations (e.g. radial velocity
estimation in stellar spectra, interpretation of the absorption features in
quasar spectra). A few months away from the instrument's first light, the DAS
is now mature for science validation, with most algorithms already implemented
and operational. In this paper, I will showcase the DAS features which are
currently employed on high-resolution HARPS and UVES spectra to assess the
scientific reliability of the recipes and their range of application. I will
give a glimpse on the science that will be possible when ESPRESSO data become
available, with a particular focus on the novel approach that has been adopted
to simultaneously fit the emission continuum and the absorption lines in the
Lyman-alpha forest of quasar spectra.
