Notes.

(a)

In units of 10−15 erg s−1 cm−2 Å−1.

(b)

In units of 10−13 erg s−1 cm−2.

(c)

The UV spectrum does not cover the 1900 Å blend.

(d)

Presents broad absorption lines in the regions of C IVλ1549+He IIλ1640 and Si IVλ1397+O IV]λ1402.

(e)

We consider BLUE+BC when estimating fluxes and equivalent widths of Al IIIλ1860 and Si III]λ1892.

(f)

This source is optically classified as Pop. B, but the UV spectrum fits perfectly with the one of a Pop. A quasar.
