Notes. Column (1): line name. Column (2): laboratory wavelength of the line in the air. Column (3): peak velocity of the broad line in the rest frame with regard to the λair. Columns (4)–(6): the line widths at 25, 50, and 75 percentiles of the line peak. Column (7): the second moment of the line profile, following the definition of the Eq. (3) of Dalla Bontà et al. (2020). Column (8): the asymmetry index (Eq. (2)). Column (9): the kurtosis index (Eq. (3)).
