Pseudo-spectra of selected sources. From left: source id: 2146 with a clear Hα + [N II] emission line complex at z = 0.387; source id: 625 with Hα (truncated in the blue side) and [N II] emission lines and [S II]λ6716 (on the red side of the spectrum) at z = 0.371; and source id: 3289, which exhibits the [S II]λλ6716,6731 doublet at z = 0.340. The green line shows the best-fit synthetic spectrum after the convolution process. See Sect. 3.2 for details.
