Notes. The abbreviations used in Column 1 consists of the name of the ion followed by a letter that indicates: “a” P Cyg absorption component; “e” emission component; “n”; “psudo” densely packed lines forming a pseudo continuum. The reference wavelength (in Å) refers either to the laboratory wavelength of the principal ion listed in Col. 3, or the center of a blend, or the midpoint of continuum bands.

(a)

The combined contribution of Fe V lines dominates over that of O V;

(b)

FeVI 1222.82, 1223.97;

(d)

FeV 1269.78, NIV 1270.27, 1272.16, FeVI 1271.10, 1272.07;

(f)

FeVI pseudo-continuum composed of densely packed Fe VI lines

(g)

FeV pseudo-continuum composed of densely packed Fe V lines.
