Note. The numbers in parentheses correspond to the abundance ratios [X/Si] and
[X/Fe] computed by considering all of the gas in the Si II and Fe II
profiles in comparison to the adopted method (see Sect. 4). a Logarithmic weighted mean of [X/Si] and [X/Fe] using their 1 
errors as weights. b Logarithmic rms dispersion in [X/Si] and [X/Fe]. c Reduced 
of [X/Si] and [X/Fe] relative to their weighted mean.
