An example of the spectral decomposition of two sources is shown here. Left panel: observation 11 from the SALT telescope (red) for HE 0413-4031 fitted with one component (blue) of MgII, FeII pseudo-continuum (magenta), and the power-law (green) representing the continuum from the accretion disc. The lower panel shows the residuals of the fit. Right panel: observation 10 from the SALT telescope (red) for HE 0435-4312 fitted with two components of MgII (blue) and the rest are the same as the left panel.
