Extracted spectra from the PMAS datacubes in a 3′′ diameter aperture. For those objects where available (Q0027+0103, Q02560003 and UM 247) SDSS DR9 spectra have been over-plotted in grey to illustrate the quality of our flux calibration. The vertical dashed line shows the wavelength of Lyα at the quasars redshift and the vertical dotted lines indicate the wavelengths of the artificial telluric Hg i (4047 and 4358 Å) emission lines.
