Notes.

^(a)

Ionisation parameter in 10^-9 W m.

^(b)

Adopted velocity based on UV lines.

^(c)

Adopted systematic uncertainty in velocity based on the differences in centroids for the UV lines.

^(d)

Statistical uncertainty observed line centroid, uncertainty in laboratory wavelength (Table 3) and the adopted systematic uncertainty in velocity have been added in quadrature.
