Notes.

(a)

Summation over all amplitudes in the velocity interval 300–800 km s-1, i.e. the integrated emission line intensity was not corrected for absorption.

(b)

Sum of one or more Gaussians fitted to the observed line profile, excluding the velocity range between 500   km   s-1 and 625   km   s-1, i.e. the integrated emission line intensity is to first order unaffected by absorption.
