Notes. The uncertainties reported are 1σ error bars. The parameters that are prefixed by a tilde are the parameters that were fit with either very large or null uncertainties in the least-squares fitting routine, which imply that these values were poorly constrained. The column density fit parameters with large uncertainties have been quoted as upper limits. Column (4) is the central wavelength of the absorber. Column (8) is the rest-frame equivalent width (E.W.) (for Si II lines only).

(a)

Si II λ1260.
