Notes.

^(a)

The two values correspond to b fixed to that of C i and that obtained when left as free parameter.

^(b)

Value from fitting the line, consistent with the [Zn/H] and [P/H] ratios. See text.

^(c)

Because O i^∗λ1304 is noisy, we fixed b to the value obtained from fitting O i^∗∗λ1306 alone.
