Notes.

(a)

Values from Gaussian fits to the lines. Numbers in parenthesis indicate 1σ uncertainties from these fits.

(b)

Velocity shift of line center relative to z = 0.010411.

(c)

FWHM of lines.

(d)

Inferred velocity width is based on the instrument resolution assuming a Gaussian profile; this is not listed for doublets that are not well separated.

(e)

Value of the fitted baseline at the line center.

(f)

Absorption lines indicated with minus sign.

(g)

The two Λ −components are (almost) blended into a single spectral feature.
