Notes. For each of them, we report the detection parameter α, the best-fit values (wavelength and line flux) and the Doppler velocities, computed with respect to the reference wavelength from the literature. Line widths were fixed to 0.003 Å if not stated otherwise.

(a)

Possible line blends include Fe XX at 10.024 Å and Ni XXIV at 10.027 Å.

(b)

Reference wavelength taken from AtomDB database (http://www.atomdb.org/index.php).

(d)

Computed from the Ne X Lyα best fit wavelength, as from Erickson (1977).

(e)

Another possible identification is the Fe XIX at 10.648 Å.

(f)

Possible line blends are: Fe XX at 11.007 Å, Na X Heι at 11.003 Å, and Fe XIX at 11.002 Å.

(h)

Another possible line is Fe XX at 11.546 Å.

(i)

Best-fit value of the line width of Å.
