Notes. Column description: (1) emission line name followed by the kinematic component: narrow (n), intermediate (i) or broad (b); (2) corresponding FWHM corrected from instrumental broadening; (3) velocity shift (Δvs) relative to the central λ of the narrow component of Paα; (4) integrated flux. Measurements without errors correspond to parameters that have been fixed.
