Notes. (1) Object’s common name. (2), (4), (7) Specific flux of the continuum emission measured at 1350 Å, 1700 Å, and 5100 Å, respectively, and measured in units of 10⁻¹⁵ erg s⁻¹ cm $^{- 2} Å^{- 1}$ $^{-2}\,{\AA}^{-1}$ . (3), (5), (6), (8) RMS of the flux associated with the continuum emission, measured in units of 10⁻¹⁵ erg s⁻¹ cm $^{- 2} Å^{- 1}$ $^{-2}\,{\AA}^{-1}$ , in the ranges of the various lines inspected in this work. (9) Absorption parameter in the V band obtained from the NED database.
