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. 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)
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
