Notes. (1) SDSS identification, (2)–(4) and (6)–(8) metallicity values estimated from CIV/HeIIλ1640, SiIV + OIV]/HeIIλ1640, and AlIII/HeIIλ1640 line ratios for fixed densities of log(nH) = 12 and 13 (in units of cm−3), respectively. (5) and (9) median metallicity values for the corresponding value of fixed density. The measurements of the six BALQ were excluded from this table.
