Title of your presentation : Determination of the quasar continuum for high redshift highly luminous quasars

Determination of the quasar continuum is important to study the absorption lines because the latter are characterized by flux-independet optical depths. This is not obvious specially at low spectral resolution and high redshift where there is little unabsorbed continuum remaining in the Lyman-alpha forest. There are different methods to normalize the quasar continuum. But no systematic comparison has been performed yet. We have made a qualitative comparison between the results obtained when applying the different methods and constrained its systematic errors.
