Average spectra of the type 1 AGN samples with the identification of the main emission lines: the lower composite spectrum (in blue) represents the type 1 sample without [Ne v] detection, while the upper composite spectrum (in red) is the average of the [Ne v]-detected type 1 AGN; the spectra are offset for clarity. The flux is given per unit wavelength (Fλ), and the normalization is arbitrary.
