Scientific paper

We present inversion techniques aiming at recovering the stellar content
(age, metallicity, extinction) and kinematics of a stellar population from its
absorption line spectrum. These techniques use new synthetic high resolution
spectra produced by PEGASE_HR and minimization algorithms. Application to SDSS
data and to a simulated disc-bulge system are presented as examples.
