(a)

Line flux ratios of N vλ1240/C ivλ1549, N vλ1240/He iiλ1640, (Si ivλ1398+O iv]λ1402)/C ivλ1549, and Al iiiλ1857/C ivλ1549. These errors are estimated by taking both random error and systematic error (five percent on line flux) into account for each emission line.

(b)

In this interval Al iiiλ1857 is not detected.
