Notes. The last column denotes the metal abundance with respect to solar.
The restframe EW (1σ errors) and the 3σ detection limits are measured assuming an aperture of 1665 km s-1, i.e. twice the full width at half maximum of a Gaussian with Doppler parameter b = 500 km s-1.
Derived from the Voigt profile fit of the Lyα absorption, see Fig. 5.
