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


Abstract
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.
