Notes.

(a)

Equivalent width.

(b)

Observed wavelength using the nominal SAS wavelength scale for RGS1, with RGS2 wavelengths shifted downwards by 6.9 mÅ.

(c)

Laboratory wavelength (experimental or theoretical) with best estimate of uncertainty.

(d)

Outflow velocity; for lines from the AGN relative to the systematic redshift of 0.034397; for lines from the ISM (labelled “G” in the first column) to the LSR velocity scale. Observed errors and errors in the laboratory wavelength have been combined. The velocities are based on the observed wavelengths of Col. 4 but corrected for the orbital motion of the Earth, and have in addition been adjusted by adding 1.8 mÅ to the observed wavelengths (see Sect. 6.4.6).

(e)

References for the laboratory wavelengths.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
