Note (2): The balnicity index is a modified velocity equivalent width of the
C IV broad absorption line. See Weymann et al., 1991ApJ...373...23W 1991ApJ...373...23W.
Note (3): The detachment index is the degree of detachment of the absorption
line relative to the emission one.
See Weymann et al. (1991ApJ...373...23W 1991ApJ...373...23W)

Global Notes:
Note (G1): Object Type is numbered as follows:
1 = non-BAL QSOs + one intermediate object
2 = HIBAL QSOs
3 = Strong LIBAL QSOs
4 = Weak LIBAL QSOs
5 = Marginal LIBAL QSOs
6 = unclassified BAL QSOs
