Notes. Column (1): Absorption trough as defined in Table 4. Column (2): Central velocity of the trough (km s⁻¹). Column (3): Lower limit on the density derived from C IV (log cm⁻³). Column (4): Upper limit on the density derived from C IV (log cm⁻³). Column (5): Lower limit on the density derived from N V (log cm⁻³). Column (6): Upper limit on the density derived from N V (log cm⁻³). Column (7): Lower limit on the density derived from O VI (log cm⁻³). Column (8): Upper limit on the density derived from O VI (log cm⁻³). Column (9): Lower limit on the distance (pc). Column (10): Upper limit on the distance (pc).

^(a)

Upper limits on density taken from Table 8 of Arav et al. (2012).

^(b)

Lower limits on distance taken from the 99% confidence limits in Table 8 of Arav et al. (2012).

^(c)

Upper limits on distance use the most stringent (highest) limits on the density from either C IV, N V, or O VI.
