Notes:
^a Balnicity index of the CIV absorption as defined in Weymann et al. (1991), which is "similar'' to the Equivalent Width of the absorption line measured in km s^-1.
^b Slope of the continuum ( $F_{\lambda}\propto \lambda ^{\alpha }$ ); this is calculated by comparison with the non-BAL SDSS template which has $\alpha = -1.61$ (see text).
^c Reddening to apply to the SDSS non-BAL template to match the observed spectrum; a SMC extinction curve is assumed (see text).
^d Absolute magnitude in the rest frame i^* band, obtained by using the observed spectral slope and assuming H₀ = 50 km s^-1 Mpc^-1, $\rm\Omega _m=1$ and $\rm\Omega _{\Lambda}=0$ (to allow for a direct comparison with Reichard et al. 2003a); it is not corrected for intrinsic absorption of the QSOs.
^e This is the redshift obtained by our spectrum, while the redshift reported in the literature is 5.09.
^f Possible FeLoBAL (see text).
^g All errors on the balnicity indices are dominated by the uncertainty on the profile of the CIV emission.
^h This is the redshift obtained by our spectrum, while Goodrich et al. (2001) report a redshift of 5.74.
ⁱ This is our best estimate of the redshift based on the MgII (which is slightly different than the redshiftof 6.23 published by Fan et al. 2003); however, the CIV and SiIV emission features may suggest an even lower redshift.
^j The extreme UV continuum of this LoBAL may be fitted with dust reddening, but with an extinction curve totally different with respect to the SMC one adopted for all other BAL (see text for details).
^k This is the redshift obtained by our spectrum, while the redshift reported in the literature is significantly different: z=4.94.
