Notes. Column 1: 4FGL name. Column 2: SDSS spectral identifier in Plate–MJD–FiberID format. Column 3: signal-to-noise ratio (S/N) of the spectrum. Column 4: redshift in SDSS. Column 5: classification based on optical spectra: F for FSRQ, B for BL Lac, L for LINER (low-ionization narrow emission-line region), and G for regular elliptical galaxy. Column 6: observed wavelength (in Å) of the emission or absorption line. Column 7: line type: E for emission lines, A for absorption lines. Column 8: line identification with rest-frame wavelength. Hα⋆ (Hβ⋆) denotes a narrow Hα (Hβ) emission line. Columns 9 and 10: redshift derived from the line in Col. 8 and its uncertainty, respectively. Columns 11 and 12: equivalent width (EW, in Å) of the line in Col. 8 and its uncertainty, respectively. Full table available at the CDS.
