Notes.

^(a)

The Si iii lines are too weak to fit without constraints, thus we fix v and σ at the values found for Lyα at the same position;

^(b)

in the G750L grating used in 1999, the Hα line is blended with [N ii] 6548 Å. This contribution is subtracted assuming the quantum mechanical ratio [N ii]6584 Å/[N ii]6548 Å = 3.0.
