Notes. For Paα (vn), (n), (i) and (b) refer to the ‘very narrow’ (only confirmed in the X-shooter spectrum), ‘narrow’, ‘intermediate’ and ‘broad’ kinematic components isolated in the spectral fits. ΔV is the velocity shift of the individual kinematic components of Paα relative to the narrow one (n), which is at the systemic zsys. ‘ns’ means noisy and ‘out’ means that the line is outside the spectral range.
