Notes.

^(⋆)

Galactic E_B−V reddening and A_λ towards the absorbing galaxy assuming the Schlafly & Finkbeiner (2011) re-calibrated extinction maps.

^(⋆⋆)

Cristiani (1987) identified emission-lines 2σ from z_abs, 7.1 arcsec from the quasar sightline. Le Brun et al. (1997) resolved the candidate into two interacting objects, the emission lines originating in one of them.

^(†)

Boissé et al. (1998), their Table 6, report a metallicity and introduced a typical uncertainty of 0.1–0.2 dex. Due to a poorly constrained N_HI, we assign a conservative error of 0.40 dex.

^(‡)

The magnitudes in Chen & Lanzetta (2003) were corrected for Schlegel & Finkbeiner Davis (1998) extinctions. Here we report the conversion to the Schlafly & Finkbeiner (2011) maps.
